The point about eating the dog food is so that you improve it
to the point where it is acceptable.

I think it is time to accept that the MBONE technology is
fatally flawed and is not going to be deployable.

Equally flawed and useless are the H.323 protocols that do not
tunnel through NAT or even work with a firewall in a remotely 
acceptable fashion.

NAT is the big bad dog here, that is what breaks the
end to end connectivity. <restart NAT war />
 
This thing is not rocket science. There are lots of folk
with the little cameras and the ISPs do not want to have
their bandwidth wasted needlessly. But trying to do multicast
in the network layer has failed. The Internet considers 
complexity in the network to be stupidity and does not route
it.

Simple solution: IPv6 tunnelbrokers that provide multicast connectivity.
2 bonuses in one go:
 - IPv6 connectivity, thus anything becomes end-2-end.
 - IPv6 Multicast connectivity, also to IPv4 using the gateway.

Then ISP's only need to upgrade their core network and can
leave the access part as what it is. But fortunatly that
is not protocol and thus has nothing to do with ietf ;)
