Just want to throw this idea out there if its possible.

Below I added a video of a NAGA grappling tourney. As you can see there's multiple 1 vs 1 matches going simultaneously.

Just like the little square mats in that video, it would be very fun to include a way to have multiple matches of aikido in one server. For example have one server with 4 aikido dojos. Each with their own spectating queue. Spectators can chose which dojo they want to fight while watching 4 different fights! This would be great for tourneys and regular 'lax playing where multiple players can play but still chat with each other.
