I tried implementing it a year/18 months or so back for an NFS mounted
Qmail mailstore for around 8000 accounts.

NFS v2/3 had been running fine off an FC-based server for a few years
but we wanted to standardise on CentOS 4. During the migration I
managed to get NFSv4 working to my satisfaction and rudimentary load
tests all seemed fine.

Under real user load though it just fell on its arse very quickly and
a quick fall back to v3 was implemented. Maybe the EL5 implementation
behaves better?
