To answer your specific question: the Internet2 Abilene network is ready
and capable of running SSM, and has been for well over a year.
That being said, the problem with SSM deployment revolves around the need
for network edge devices like switches and routers to support IGMPv3. It's
difficult to find Ethernet switches that support IGMPv3, and they're not
the most economical choices.
In a strange inversion of the normal situation, the backbone is capable of
SSM service well before the local area networks of the connected sites. If
you can find a site that supports SSM/IGMPv3 locally, it's a pretty good
bet that they can do SSM with most all other similar sites.
