i have just the setup, and an ultra1 as the file server, so i may be able
   to run some tests against sol8 or 9. [not sure if those are the best choices
   for ultra1 to compare against netbsd or freebsd, but at least they both come
   with a freeware cd... :)]


it would be useful to know how netbsd performs as an NFS server 
compared to solaris.  solaris NFS server performs pretty well in
my experience...
