To follow up on what @agibsonccc has been saying: Remote, open-source hiring is one of the best ways to match companies and candidates. I used to have to recruit for a closed-source company, and it was really hard to get good information - for the company and for the applicants.
In open-source, you have nearly perfect information: the contributors see the company's code and how they operate as a team; the company see the contributor's code, persistence, reliability and friendliness. And anyway, it's open-source, so everyone is solving their own problems for their own reasons, so they get something out of it in the end no matter what.
