OK, that sounds complicated, but if it would work, than it would be very nice indeed.

But NFSv4 is still exprerimental :-( and i think the client don't have NFSv4 support too.

Sorry? Why is my server broken? I'm using kernel 2.6.8.1 with nfs-utils 1.0.6 on my server, and i don't see, what should be broken.
