Well, we have all the hardware we need to run them locally, and we don't want
to bog our network down (it's slow enough as it is without 279 diskless
workstations booting up at once), so running them right off the hard disk is
actually our ideal situation.
I appreciate learning about stuff, though, so thanks for your suggestion.

There is such a thing as diskless clients which run all of their own
applications. This might suit your requirements well. The idea being that
you provide a PXE boot image and then an NFS shares with home dir and
system image. Then the desktops do all the work. This might work well for
you because:
- it'll make use of all of your good cpus
- adding new machines involves zero install, you just plug them in and PXE
boot them
- client disk failures are not an issue
- installation of software is only done in one place
- home directories are stored centrally (although that's easy enough to
arrange with nfs anyway)
- you get much better performance on video, sound, etc. as the data
doesn't have to stream across the network
I don't think edubuntu supports this mode of operation at the minute, but
I imagine it could. One implementation is called lessdisks, LTSP has
something called LOCAL_APPS, though I'm not sure exactly what that does.
If that would be your ideal Edubuntu setup, maybe you could propose working
on a project to implement that. I'm only another user of course, it's
possible the Edubuntu people will think this a horrible idea.
