Because I wasn't foresighted enough?

Anyway it would be nice to fix this now (if only to save me from more
embarassment as people keep asking about it).  This isn't a case of
"now or never" but since nobody has even proposed a start date for
work on an NFS-v4.1, it is a case of "now or some time after 2005",
which isn't very attractive either.

My big concern with adding anything at this point is the workload
for our editor, and the possiblity of delaying even further the new
hopefully final Proposed Standard.  This isn't a big thing but given
where we are now, every little bit hurts.

As a way of ameliorating this concern, could we have a volunteer (like
Jim perhaps) who would come up with a set of precise spec updates (at
essentially the level of diffs) ready to go in if there is consensus
on this issue.

And it would be so easy to fix, for example by specifying that the reserved
r_addr "--SOURCE--" means that callbacks should go back to the source.  It's
one thing to say that callbacks aren't required for proper operation, but to
prohibit their use from behind a nat is a shame.
