NFS has no real idea about user authentication and uses ipaddresses, in 
other words, you are going to have problems, at least I did when I tried 
it once. It may be different now, but I doubt it. If you are going to 
share an nfs share, just do it with nfs.

True for NFSv3, not for NFSv4.

Good advice, but mostly because NFS doesn't map completely to
POSIX semantics, and it also means the data goes over the
wire twice. Having said that, sometimes people need to do
this (the Amazon NFS user is a case in point) so we should
track down and help fix the problems when we can.
