How are you handling authentication?  The uid numbers for the
same user must match between the server where they log in and
NFS server.  If you aren't using NIS or LDAP you will have to
make sure the user entries are identical in the /etc/passwd
and /etc/shadow files.

You'll probably need to get all the servers on a gigabit backbone to
make this scale very well.  Otherwise it would be better to use
a dual-nic configuration with a certain number of clients behind
each server to split up the bandwidth.  You'd still be able to
log in anywhere and find the same home directory.
