I don't see any immediate problems with this.
It might be nice to add a command line option to select which
transport to use, but that's entirely optional.

First (and quick) attempt at a patch here for showmount. Let me know
if you see
serious problems with it or the approach. It seemed relatively sane
to me and
fixed my problems after brief testing.
See a report like this for some proof this is an issue in the wild:

Thanks,
