I've read both the version you told PG, and what you say you should have said a number of times and I still don't get it.
It sounds like Google Wave. I'm not sure if that is a good thing or a bad thing, but it sounds like you are having the same problem they had: explaining what the hell it does.
When I tried to explain Wave to people I said it was a combination of the ideas of Wiki, email, chat and a forum, designed to make accomplishing shared work easier. It's still not great, but I don't think it's an easy thing to communicate.
