Toerless Eckert from Cisco talked to me about this at IETF last week in London.

He suggested that we should look into using VPN server boxes and VPN client 
software to provide this functionality where necessary.  The VPN servers 
are already scaling to 100s and 1000s of clients, and are off-the-shelf.

Of course I agree with Bob: the best alternative is to get native multicast 
properly deployed to the various sites.
