Seems like an easy application for fs_locations{_info?}.  It'd need
server support too, and I think you probably want this manual method as
well for now.

I wonder if the server can easily generate a list of IP addresses to
advertise automatically?  In which case the whole thing would be
zero-configuration, which would be nice.

pNFS sounds like overkill.
