Just wanted to say I read most of the threads here (tho lack knowledge to truly grasp many of the topics or info given). This thread,  though does make me want to respond and say how intriguingly awesome the context and conversation is ;)

Oh, excellent! I really didn't expect anyone would be, and getting anyone's attention from the outside is generally difficult with these sorts of things... "Hi, I'm a network guy from another country who you don't know, and I want to talk to you about your multicast enabled cash registers."
