I want to make sure that I've got this right.  In theory, I should be 
capable of netbooting from NFS, a *diskless* client to run slaved 
backend and frontend processes that's local to the thin client.   This 
implies I only need to administrate only the NFS server (possibly w/ 
some XF86Config files local to the thin clients).

Any estimates what housepower(memory) would be necessary?
