Ethan Lee worked on this! Ethan Lee is an awesome person. Ethan is probably the single biggest contributor to gaming on Linux, and he's always worked in the background. Thanks Ethan, you rock, and deserve more credit.
Maybe I've just been out of the scene too long, but can't let mention of Linux gaming luminaries go without Ryan C. Gordon of Loki Games/icculus.org. For many years, if there was a big project coming to Linux, Ryan Gordon was likely to be the wizard behind it.
It's fantastic that he provided a place to host code for game modders / developers as well, I definitely spent years of my life playing http://svn.icculus.org/tremulous/
That's an impressive collection of Indie games. This looks like the classic example of a consultant gig. You have some specialized knowledge of how to solve a problem that's easy when you know what you're doing. Indie devs can hire you for a day and check off that "Linux support" box so they can show up in a Humble Bundle and make a little more than you spent on the consultant with those 5% or so Linux gamers.
