You're asking the wrong question; you should say, "Does such a directory 
exist any more?" There used to be several places to look for active multicast 
streams, but AFAIK they're all offline now. That's matched by the decline in 
active multicast sources; very few are still online. 

You can always fire up VLC and watch SAP announcements, though I just checked 
that list and only found two live streams (NRC 1 and 2). Much of what gets 
into the global SAP list is actually leaking out from campuses; the groups 
themselves are admin-scoped and aren't visible, but the announcements 
propagate globally.
