Team 2 is ready. The shipset I'm using isn't on PBW yet, apparently. It is the
Derajil, one of Atrocities' shipsets for the Race to SEV tournament.
How about a gentleman's agreement to only use warp openers if your team already has a colony on both sides of the new warp point? Closers get the same restriction plus a requirement to leave at least two routes into your side's territory and never completely isolate any section of the galaxy from the rest.
