Why does PartyMine want to talk to the internet?

I posted this on the PartyMine forums:

When it starts up, PartyMine tries to connect to a site on the internet. If I let it connect, it then tries to act as a server. Why?

Oh, and the obligatory thanks: this is really useful, has a nice, clean interface and is very easy to use. Thanks!

but haven't gotten a reply yet. My firewall is keeping PartyMine from talking to the outside world, but I'm still curious. Anyone know the answer?
