Good points Bill. I can't speak for anyone else, but using SAPs is  
one more way for a small school like ours to make our streams known  
and available to the rest of the multicast-enabled world. Until  
something better comes along, the self-discovery feature is very  
valuable.

I admit SAPs have been abused, especially recently...many of the SAPs  
are inactive, and the SAP storms have been very disruptive to some  
institutions. But I don't see any other available choices at this  
time. Maybe the resurgence of storms is a reflection of an increase  
in interest in being able to advertise one's programs in an intuitive  
manner. Click on the SAP, and watch the show.

We would like to keep using them, if possible, for our streams. Of  
course, if SAPs are blocked by networks, they won't be much good! But  
there has to be a way of dealing with the storms...and hopefully the  
SAPs that don't have streams.
