Cool idea!  Actually, in hindsight I think they had it right
in the 70s.  Heck of a lot easier to administer than a bunch
of PCs all over the building.  So I can see why you're
wondering.  It CAN be done but I've never done it. 
Basically
it involves exporting the virtual consoles in linux to
physical consoles (Wyse terminals essentially) out the
serial
port.  In theory you could run multiple X sessions also this
way.  Just set yourself up with a monsterous 1.33 Ghz
(overclocked of course) and a gig of RAM and you have a nice
thin client solution for 4-6 users.  Has anyone here tried
something like this?
