If some machine foo mounts I ran into this when I was working with glusterfs earlier this year - in my case, the glusterfs was on the nodes of a cluster, and I wanted to allow it to be mounted from the head node, and not have to talk to all the nodes. The answer was unfs, which *will* re-export. I *think* NFS v4 will also do reexports. mark
