Hi David,

Don't try the beacon viewer; the number of sources exceeds its capacity.

Go to http://beaconserver.accessgrid.org:9999

Or, to see a subset, go to

       http://water.mcs.anl.gov/~olson/beacon-php/beacon.php

and pick the sources you're interested in seeing.

Now, with respect to multicast service to usm.edu.  At this point it looks 
like BGP NLRI=Multicast is not yet properly configured between you and 
Abilene.  Here's what the Indianapolis Abilene Core node sees on the 
peering with you:

There does not appear to be an MSDP peering between you and Abilene.
There does not appear to be a PIM-SM adjacency between you and Abilene.

I would recommend looking at

    http://www.abilene.iu.edu/index.cgi?page=mc-cookbook

for examples of how you need to configure your Abilene peering router to 
turn on multicast out of your network, including Multiprotocol BGP, MSDP, 
and PIM-Sparse Mode.
