What about the idea of clustering the 150 doing that along with clustering
the machines with openmosix?
Just a thought :)

3GB / 150 workstations = 20MB per workstation. I don't think this is
enough. With 150 copies of the Gimp and OpenOffice, you're going to need
something like 32GB of RAM on the server.
To make that easier to attain, I would consider a two-tier server
network:
1) an NFS server to host home directories, dhpc, dns, etc. This server
needs lots of disk and a tape backup unit, but not a lot of RAM or CPU power
(say 512MB of RAM and a single CPU).
2) two or more servers with lots of RAM and CPU but very little disk space
(enough for the O/S and apps).
This lets you spread the load out. You can split users into groups (editing
room, office, reporters, etc) or you can put one app on each server (eg,
Gimp server, OpenOffice server). The servers mount /home from the first
server, so no matter which second-tier server you use you get the same
files.
