Thanks.  I had checked out the Linux userspace NFS daemon but missed
this one.

I'm trying it out now.  It does allow re-exporting.  My initial sanity
test using a VM as the relay (time cat 821MB-file > /dev/null) shows
that the re-exported system is about 70% of direct mount speed, with the
iostat measured NFS reads/s peaking at 60%.  This clearly warrants
further testing.
