there's been a couple of papers kicking around on how to do multiple
sender multicast with ssm

here's a thought not original based on them 

given some of us actualyl have operational wide area nets with PIM SM
running, fairly well, but our experience with  wider area
(interdomain) is just basically hopeless,
how could we leverage SSM as an inter-domain protocol for
multiple source multicast?

seems quite simple really....esp. if you are prepared to aggregate
traffic from all sources for a group (and possibly all sources for
multiple groups) into an SSM tunnel, that sources all traffic from a
domain as a multiplex, to all other domains that agree (subject to
policy) they are interested

so we still need the MSDP stuff, but it needs to be IGMPv3ized so to
speak so that it can be used to manage filters for a bundle of SSM
interdomain tunnels....

nice thing is that all sorts of interdomain traffic engineering then
becomes quite cute too

just a thort



 cheers
