Live feed: One per battle, multiple computers. Skype again? Or a broadcast yourself site? Perhaps everyone brings a laptop and we have live feeds from all battles, including the UK, recording.
Battle Reporters: The guys [and girl] with the best cameras and battle report skills. Need a good camera and a notebook.
Brik Masters: One or two per table, solves arguments concerning rules, homebrews, and whatnot.
Homebrews: Stats, abilities, and tacked-on rules that aren't in the rulebook would need to be posted here beforehand for approval. Nobody plays Brikwars in exactly the same way, obviously.
Exactly how intent are we on doing this? Because I think it really needs to happen. Time will tell if we can get this vetted to be an official event [NELUG] or something, giving parents something to see saying 'oh, it's official, it's not just little Timmy wanting to go and meet a bunch of his weird internet friends.'
