A suggestion:
Why not hold three summits linked by Webcam or video telecom or something. The first is in the US. Have it in a city central to the US members. I'd offer that Chicago or Denver would be a fine place (or, I'd be happy to work the logistics of a Macon, Georgia, summit location, since I'm here and Macon is in desperate need of tourism).
The second summit would in London. London's a good international hopping off spot for any number of folks in the European theater and makes for easy air travel.
Finally, a third summit in Australia at a location central to the Oceania residents.
Again, have all three simultaneously (though the 14-hour time difference might make partying via Webcam a bit tough). Have contacts at each location act as logistics and plans chiefs to set them up (certainly amogst the legion of Jenna faithful, there be three who'd step up to build a meeting). Finally, use technology to link the three -- this forum, Webcam and whatever else might seem feasible.
Sounds like a gradiose idea, but, really, it's just three meetings at the same time in different locations with the same name. It would, as the kids say, be the shizzle. A hoot. Grand. And what a coup for AbWr.
And, yes, I volunteer in whatever capacity I could be used (logistics or countersniper cover)
Hugs.
