Also, providing your enhancements to a pay-to-play service might be a violation of the original code release EULA, wouldn't it?
I'm sure not enthused about Gametap, personally. When they picked up Tachyon: The Fringe, Novalogic locked us all out of any way to host private games, and changed it so only their "official" server could be used. There's also a specific clause in the EULA that forbids anyone from creating a 3rd-party hosting/matchmaking service for the game.
However, most of that is just typical Novalogic. They have a tendency to use a sledgehammer to crush an annoying fly.
