damnit....why does debian have to be so god damned easy?
I was half hopeing I would have to download it as source and
find out it wont compile and have to laborously install it...sigh...

It will...I never noticed :)

That does sound like a great idea... It should also have some mechanism
for keeping a database of how many XTerminals are currently "up"
and what their adresses are....I would like to be able to (via a
custom script or program....id like an X interface ;) ) be able
to broadcast a command to all of them...sort of in the form
xterminals broadcast "shutdown -r now"
or xterminals dumbass "shutdown -r now"
(right now thats the only command I can think of)
ssh would also be usefull if I wanted to set up pvm on them ;)

Actually...I had thought maybe each xterm already has /floppy (as virtue
of being from the debian base system)...
If there was a command that would allow them to put in a request to the
host...which would then automatically ssh in to the xterminal and mount the
floppy (or unmount it) then half the work is done right there
hmm maybe have the xterminals have just a sym link in /etc for exports
linkin gback to /tmp (since it is the ONLY thing writable) and as part
of the xdm login process it could ssh in to the xterminal...
write the proper exports (simple export /floppy back to the same server
that is running)
then on the host machine just mount that nfs mount in the users ~/floppy
(if they have one...) maybe add logic to the flioppy mount script
to check fo rthe existance of ~/floppy and make/mount it on the
fly
