No we do everything via NFS at the moment. Using a big ramdisk would
cut
into why all the machines have so much memory and CPU's. Basically the
idea is that all CPU cycles are local and all data is foreign. The
approach to this seems to follow either SGI or Sun ways of doing
diskless clients. I like the Sun way of doing it (with each client
getting its own tree) versus the SGI where most is common with the
server and clients need a rebuild if server code changes.
Can a user move to another workstation and resume their session? I've seen
this done with RFID tags that automatically detach your session if you
move away from the terminal and re-attach you when you move closer.
