that definition of working "fine" doesn't work for my campus. berkeley
researchers are investigating the use of relatively high-bandwidth
multicast (>10Mbps per stream) and i really don't want that flooding
on departmental segments with one receiver. other Internet2-connected
institutions are in similar positions, i think.

i agree with Bill's earlier comment: lack of IGMPv3 snooping in current
switches is a major obstacle to IPv4 SSM deployment, and lack of MLD
snooping will become an impediment to IPv6 SSM deployment.

i sure would like to have SSM too...
