I admit I overlooked that one (16 vs 32 bits). But if I'm not mistaken, NFS does not care a bit about the name of the user "nobody" or the UID in /etc/passwd or what-have-you. It simply sets the UID of remote root (UID 0) to the value -1. And 4294967294 happens to be -1 in 32 bits signed. So - possibly this is built into ZFS this way. I would at least give the sharenfs="..." options a try ...
