Maybe focus on the chat sessions? The site really isn't moving that fast these days. There are some site designs being posted, but as far as I know, no coding, and absolutely no progress towards location and legal decisions. In other words, there's not much of a rush for you to jump into anything.
Thinking out loud, I don't know if we really need to worry too much about setting the site location just yet, because I assume we could move easily enough in the first days/ weeks/ months of the site. I doubt we'd have any legal questions / issues when we're small, unless we jump into risky grounds (maybe we hold off on accepting images that might cause a ruckus, or host it off-site). Of course, hosting images requires we have some site that will utilize images, so we're safe there still =)
