Yes, filtering or failing to distribute IGMP is probably one of the
biggest roadblocks for multicast.  There needs to be some killer app
for multicast to be written to get admins to support it.  A lot of
online music streaming services could benefit from it a great deal.
It would also help ISPs to minimize traffic associated with this and
other live streaming apps, including MMORPGs, etc.
