I was about to say "yes" until I looked at the IP multicast beacon 
reporting web page at

   http://beaconserver.accessgrid.org:9999

While the routing seems to be working, we are seeing packet loss of 30% or 
more both getting into and getting out of SDSC.  This isn't just to ACCESS 
so I'm pretty sure it's an SDSC-specific problem.

As always I stand ready to help.  Just let me know how.
