[K12OSN] K12LTSP Over Dialup

This statement makes me wonder about LTSP:
" The whole concept of thin clients requires a fast connection to the
server to work.  "

Here is something I read about using VNC with Linux:
"You would be shocked at how little bandwidth is required to do such a
thing. For efficiency disable all screen savers and set the desktop
background to a neutral wallpaper with no fancy stuff. I run on machine
with 120 users on it and the bandwidth used is about 200k average. X is
incredibly efficient as long as you can keep the necessary screen
refresh rates down by not running too much eye candy."

The whole concept of thin clients requires a fast connection to the
server to work.  If you only have one person at each office,
consider some other topology.  If you have several people at each
office it would work to have a suitably sized local server and
several thin clients at each.  If you just want to avoid
software installs at the remote site you might run a live-CD
linux version like Knoppix.   56k is OK for occasional email
transfers or working in character mode.  It's not fast enough
to run typical GUI programs over or even loading/saving data
for everyday use.  You'll either want DSL/cable modem speeds
for each office, or do most work locally, or special applications
written with low bandwidth in mind.
