>What are the chances mrouted could be so enlightened?

Well, what you really want is for the mrouter on the server end to just
treat your machine like a client and use IGMP to discover its group
memberships.  This requires mrouted to be modified in several ways:
- Use longest-match instead of first-match when determining the vif for
a packet
- Use the remote end of the ppp link when joining and sending to the
group, since you can't uniquely identify it with its local address
- Treat a ppp link as a host route to the remote end, instead of as
a subnet.

I am working on some of these modifications (and kernel mods to help)
but I don't see being finished any time soon; the new mrouted is suffering
horribly from feeping creaturism and I'm having a hard time just figuring
out where all the bugs are...
