I am a consultant for a large law firm in Orlando, Fl. I have been 
asked to do some research into Linux Clustering. to be specific, the 
vision is to setup a linux cluster, run VMWare on the cluster, then 
run Microsoft / Novell servers in VMWare.

If that is possible, then is it possible to add all 200+ workstations 
to the cluster and run the desktop OS (Win XP / Win 98) on top of 
that? Thus creating a cluster in the neighborhood of 243 nodes.
