My understanding of NFSv4 is that it is not NFS.  It is something new
and complicated that is way beyond what previous NFS versions did.
Sure it's called NFS, but it's different.

I too looked at it, got to kerberos, and then went the other direction.

NFS before v4 were invented at SUN.  NFS v4 was done by the IETF.  It was
based on ideas from AFS and SMB/CIFS.

I found something that seems to indicate it is possible to make NFSv4
run without kerberos and all that:
