I would ignore multicast ane let it go thru as aparently
regular dialup and ADSL users have no access to it. Thus
I consider it to be more secured by ISPs.
Streaming audio/video, is not there some "feedback" channel
so that server knows when client is dead ? There should be
something like it IMHO. Note that I'd could every packet
going to host (ignoring tcp/udp and/or port difference).

Also thanks to Gerry to take it so seriously. I'm interested
in result - especialy because I got the idea in night while
being tortured by gnats ;-)
