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? Will.
