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.
