For that I would suggest using a central LDAP repository for your idmap 
backend on all machines.  If that's all you need to do to get it going 
with nfs, that's a not-too-tough situation to solve.  You don't have to 
go through the (somtimes painful) samba/ldap setup, you just need a 
basic ldap server with one idmap tree in it.  What are you using for 
your unix auth now?  since it sounds like you've got a few unix 
machines, ldap is a good fit there too, unless you've got something else 
that's tied in to your organization that you'd have to rebuild...

What is enforcing your quotas?  2K or unix machine?
