	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.
