Right.

Yes, and until it was demanded at the San Jose IETF that I include
support for multicast servers my I-D was focussed on VC meshes only.

They have nothing to say about 1577, that is a unicast-only solution.
1483 has been at 'Proposed' standard status for awhile, which is
designed exactly to flesh out problems.

Yes, multicast servers are a problem. However, I got burned at Danvers
for suggesting people throw them away if the reflected packets were
to become a problem. So, the demand is there. Feel free to battle
on, I say.
