Okay, to get slightly more realistic, here's mys suggestion:

An Org rally point is assigned on all major continents -- North America, South America, Europe, Ostralyah and Asia. We make the rally points as central and easy-to-get-to as possible. I'm guessing that we would only need three at the end of the day, Merica, Yurup and Ostralyah.

Anyway, we set up three-way videoconferencing at all three sites. We settle on a time, and everyone arrives at their rally location, gets roaring drunk, yells into the videoconferencing.

Sounds like a plan to me.
