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...
