I already suggested a possible solution to this, Allicloud. As most of the members are concentrated in America and Europe, we conduct a poll (one for Europe, one for America), and figure out at most three locations in America, and probably two in Europe, if not three, where we would select as "gathering sites" based on demographics. If you can make it, fine, (though I'd think with that amount it shouldn't be much of an issue), and yes, there will be SOME people who can't, either due to monetary or placement issues, but by and large, I think between five to six meeting sites spread out on either continent is doable. It'd be based on what's most convenient for the majority, and where everyone is spread out. Even just two (one in the US, though I think there should be at least one other) meeting sites are feasible for something like this, if people feel like starting off smaller to see how it works. Sort of like giving the initial year a "test run", and we can always expand it if it is successful, or revise it if it's not.
And don't get me wrong, this is just one suggestion I've given. My ideas aren't set in stone.
As said, I'm not going to be doing ANYTHING towards even starting to consider arranging a meeting until I get my exam results. It's just too far in advance for me at the moment, and I'm merely suggesting things to see how they go.
Once the groups settle on places they'll be staying, a lot of places that have group rates include teleconferencing equipment as part of the package deal, so that should solve the lack of webcams or other equipment if we run into those issues.
And there is one Aussie that just joined us recently, Mumbling.
