Referring to SAP listeners. Sorry, I don't know that for a fact, if anyone 
has the answer, I'd like to hear it.

I am using the "Home TV model" for my comparison to discovering and viewing 
multicast videos.
But is it really the best one to apply? If not, I'd like to hear other models.

Also, working things backwards, how much kilobit/sec SAP traffic would be 
acceptable to network administrators?
That would help guide good practices, and predict when the SAP announce 
system would be topped off or saturated.
It is obviously not going to scale infinitely. How many channels can it be 
reasonably be expted to scale to?

Thanks,
Frank
