I think the people behind this .gay domain idea should talk to the .xxx people and ask them how long it will take to get this off the ground.
You already own dotgay.com. Why not just create travel.dotgay.com, and so on, without applying for a new top-level domain? It's not the same--you're subject to whatever .com is subject to. (Instead we'll be) in the island of .gay, which will have its own policies and be able to police people who are abusive. There's a big difference between being a site versus a place where multiple sites can exist.
