Hmm...why not just use MS Netmeeting? Seems easy enough, and on a network, it
would be pretty smooth.

Now, what about a platform so simple that allows you to do it easily?
It exist and uses only 4 letters in its name, starts with "U", ends with
"X".
Now, you see that people are looking for how to do things in a difficult
way under Windows platform, that is basicaly native in UNIX, now, that
*IS* UNIX talking, isn't it? some day... some day I will get rid of
those blue screens... :), nothing is forever, remember the Roman Empire,
and so others. If I would bet if Microsoft would still climbing and
getting powerful and powerful? Not a chance. You can't keep getting fat
forever... one day you ending up not moving anymore or so heavy that
will break your legs...

<x-flowed>Interesting. I'm just beginning to learn about UNIX. I knew you could
run Microsoft Word under Wabi, but can you really run MS Word and project the
screen image across the network to appear on other workstations?
How do you implement that?

I think you can do this with "back orifice"... Whoops, what did I said :
"Back Orifice? ARE U CRAZY? This is some kind of virus!"
The last releases seem to be +- clean, and provide video screen capture
accross network (and internet). And it's free too.
The funny thing is that if you install this, you'll have total control
of the teacher's pc...
anyone has experience with this? (other than hacking other's computers)

What Miguel wants is a simple 1k program that send broadcasting packets
copying the VGA buffer from one particular machine. It could be
distributed via Ethernet or by a simple 3 wires cable (RS485). The
viewers would be using the receiver part of the same program, and simply
displaying this data. By programming point of view, this is a very,
very simple program.
It doesn't require a 10 Mega Bytes program as NetMeeting or something
like that.
By the way, for long distance audio conversations I tested Netmeeting
(Microsoft), to lazy, to heavy, to slow, tested also Iphone5.0
(Vocaltec), but Iphone4.5 ($50 license) is much faster and reliable.
Ended up using MediaRing (SoundBlaster), much better sound quality and
it is free.

Um. NO. Since a typical VGA buffer is about a megabyte worth of data, you
want something quite a lot better than simply dumping it on a net as fast as
you can.
This IS the sort of thing that PC Anywhere is supposed to do, I think
(someone who's actually used it mentioned it as well.) It's original
purpose was to access your "office" machine from somewhere else, so I'm
not sure it will "push" a screen to multiplle "slaves" in a network.
(That'd be a logical way for it to go.)
There's always VGA->TV->broadcast video using iptv or somesuch. I doubt
whether you'd preserve enough resolution for this to work "well."

>>>>This IS the sort of thing that PC Anywhere is supposed to do
If you are looking at PC Anywhere, you might want to check out Remote
Administrator. I don't think it allows multiple sessions, but computers can
be linked. (The teachers machine is a server and the rest become viewer &
server to the next)
It is much cheaper then PC Anywhere and it is suppose to be faster. It has a
30 day demo so you can give it a try.
YMMV

Hi,
I think what you need is VNC. Its freely downloadable. Works on unix,
mac, nt and windows and uses TCP/IP.
To connect with multiple clients, you must set the clients to
listen-only.

Try VNC, it is free and does exactly this:

I believe he did, Netmeeting allows you to share an application with
another person and does exactly what you describe. TTYL

Try VNC, it is free and does exactly this:
http://www.uk.research.att.com/vnc/, the clients can access the host with a
150k client or with a Java enabled browser. TTYL

Sadly, very few apps are written in Assembler anymore. In fact, only
the good ones... ;-)

As Bill W mentions, this is *not* the way to go. An approximation
would be to send *changes* to the video buffer, compressed at least
using Run Length Encoding, which used to be the "neat" way to do this
exact task on text screens, but even that is impractical on a 8- or 16-
bit graphics screen at 1024 x 768 which are 786,432 or 1,572,864 bytes
respectively (*that's* why you can't run with less than 2M video
memory).
What you actually have to do is to "play Windows". Windows paints the
screen by means of a stream of API calls, only *some* of which contain
block data for graphics. The trick is to send not screen data, but the
API calls which painted the screen on the sending computer in the first
place.
As has been mentioned, while this can be patched into M$ Windoze, it
is the *native* structure of the X-server which makes no a priori
expectations about whether the "terminal" (screen & keyboard) are in
fact the local machine, and will just as happily connect, or tee, over
whatever network structure is present.
Clients such as Xwin32 and M$Win X-servers are available to run on
Windoze. Not that this helps the current concern.

As noted, it isn't *quite* that simple. Such things never are. And
Ethernet and RS-485 are very different bandwidths. The "raw" sending
proposal is fairly viable over Ethernet.
(Aside: My present interest is in transmitting a presentation,
presently done using Power Point, down the length of a church hall so
that the control of the presentation is with the "sound crew",
effectively the audio-visual presentation manager nowadays, and the
video projector is fed by a slave PC at the front.
This may sound turned-about, but it's quite a big hall and the video
projector is quite challenged to provide a bright picture already. My
base proposal is Ethernet via twisted pair. I'm wondering whether it
may be practical to run an app on the "master" which interprets the
display into X-server code and have the slave run an efficient Linux
X-system on a turnkey 386 or 486.)

Hmm. So what linux application can I use to mirror my X windows screen
to a bunch of students? I use X all the time, but I haven't run into such
an application (or looked for one, really...)
X tends to run over TCP, which is "multicast challenged", yes?

There are multicast "group" addressing modes in IP. An application on the
client issues its TCP/IP stack a command to join a specific group.
Voila.

There are multicast "group" addressing modes in IP. An application on
the client issues its TCP/IP stack a command to join a specific group.
The IP part of TCP/IP has multicast capabilities. TCP as the "transport
layer" reliable protocol does not include multicast. I think there is a
multicast reliable stream protocol (experimental) analagous to TCP, but X,
as far as I know, is pretty married to TCP itself. (All that display
independence, and stuck with a single network protocol. Sigh.)

PS: Just wrote an application for cisco access servers that can multicast
data from async lines (using raw, unreliable UDP protocols.) So when I say
"TCP doesn't support multicast", there's a bit of experience behind it.
