Righto.

Except that the reply might blow the libc 8800 byte limit for
UDP RPC replies (I've seen this happen).

Indeed.

So it seems an approach that would work is to a broadcast
RPC call to MOUNT NULL followed by showmount -e to each
of the repliers.  Something like...

/usr/sbin/rpcinfo -b mountd 1 | while read IPADDR NAME ; do
    showmount -e --no-headers $NAME | ...
done
