Ok, I have been asked to determine if it makes sense to acquire a lab

they are not being used for video/audio processing classes. I know I
could configure them to mount home directories for users but that is
not what I'm being asked about.  I'd prefer to stay with thin clients
except as far as I know there aren't any simple, easy-to-use
video/audio editing packages that 'just work' on thin clients. This is
for grades 5-8.  Perhaps the ability to run local apps with K12Linux
solves this?


I wouldn't do AV editing on thin clients. In general, it's one of the more demanding things a client can do. Also, why buy expensive, high end macines if you aren't going to use that kind of performance. What you CAN do is buy lab of iMacs, just enough for AV editing (or any other really intensive applications), and hook them up as workstations that authenticate using LDAP and allow users access to their home file system using NFS, CIFS, or AFP etc. What I usually recommend in a school setting, is putting LDAP and NFS and/or CIFS home directories on a central server, probably CENTOS5, or something else really stable. It doesn't need a ton of horse power, mostly just RAM and and really good storage system (like raid 5 on some fast disks. Then your iMacs and the server(s) for your thin client lab(s) can authenticate and share storage on a central system. This also let's you run the latest/greatest LTSP on your thin clients without mucking around with their logins and data, since you keep that on a more stable server (makes upgrading the thin client server easier too, since there isn't much important data on it.
