Should be quite doable depending on hardware and time.

I also prefer Debian and all my LTSP experience is Debian based.....I
choose dhcp over bootp for most things (although I think ended up doing
bootp for an old sun once at home [really interesting to see an old sun
box running as a diskless workstation :) ]
I went with gdm for my xdm management and have been very happy with it.
I'm sure you are familiar with how to get all your favorite desktop toys
using debian ;)

Great, if you have specific questions I'd be happy to help. By the way
where are you doing all this physically? Maybe I can come play too :)

And it works over LTSP, i've done it.... if you are using a 10bT as
opposed to 100bT it can be quite jerky. The 100bT plays pretty well,
unless netraffic gets nuts.
A room full of people playing frozenbubbles is quite cool. Especially
when you can reboot the machines without the floppy and everything that
was already there in that lab goes back to being it's old (mostly useless
but keeps the management happy) self....

I never got tuxracer to go over the LTSP, although I believe that was a
lack of available hardware as opposed to technical impossibility (that is
definately something I would like see... running 3d opengl programs
through the net)

Yes, pretty much all of them... they work phenomenonly well. Solarfox had
some timing issues due to the fast screen redraws it likes to do, yet it
too was playable over 100 base. I think there was at least one game that
was pretty much not playable, however I can't recall which one it was.

Hmmm, i can't recall if I put the flash extensions into the browsers over
the ltsp and/or which results they had. I think that I did get flash to
work properly although there were definately some strangeness with a
couple of applications (notably evolution) that would NOT honor the X11
server number and end up only displaying on the first screen a particular
user logged in on [would be really bad in situation where the screens were
not located in the same physical room].
> Video seems to work best locally.
xine over ltsp actually worked (but was way too slow [that particular
experiment was over 10 base though, so 100 base MIGHT make it decent] to
be of any use). With gigabit network it seems it would work well.
although multiple clients might just drive the network into apoplexy.
There is a video player that was using a streaming protocal that seemed to
make better sense than xine did, but for some reason I could not get it
work over the ltsp the way I thought it should.
There is a nice gui front end to accessing the floppy (on the client) that
works really well over ltsp, although I can't think of it's name at the
moment. I never tried to get access to the cdrom (on the client).

It probably is.

What I have done in the past (for printing out gutenberg books for my
children to read) is pull it into LyX and use LyX to do the necessary
formatting (sometimes adding table of contents, etc) which LyX makes
simple and easy yet time consuming and frankly boring....However after
doing that ONCE and looking at the resulting output file. It's very easy
to see what has been added and where (looks about like html). At that
point I use vim's macro functions to locate all the proper places and put
in the proper text substitions to make it have page breaks and numbering.
Which is simple, easy, and not particularly boring....However I'm sure a
sed or awk or even perl program would be better IF you could generacize
the process. (Given my own efforts to write a php program to
automagically html'ize gutenberg texts, I'm guessing that the above task
is much harder than it would first appear)

What's the name of the Windows VNC Client? that could also work. You can
set up the vnc server on the ltsp to come up upon demand like an http
daemon (yes i have done this and it does work). There is a description of
how to do it somewhere out there on the net, If you can't find it and you
wish to try it, let me know and I'll look it up.
Good Luck and keep us informed on how it's going.
