I think this is largely inertial.  This is one of the RFCs that the tcpm
WG over in teh IETF is hoping to advance to DS, but the problem is
interested competent manpower.  If you'd like to join that set, we'd
love to have you.  I'd express that interest over in the tcpm mailing
list.   I know you know where it is. :-)

If any of the authors of 2581 would like to pipe up here or on tcpm and
tell me I'm wrong, I won't be offended.
