I think you have.

Nope. ER does not work with large scale multicast.

Note also that multicast routing table can not be aggregated,
which makes inter-/intra- domain separation of QoSR
meaningless.

That is, you can't say you can ignore scalability issues of QOSPF
by flow aggregation.

It, of course, is a bad idea to use RSVP to let multicast members
know about all the pathes to all the other members.
