Sorry, I wasn't aware of the guest account thing. Probably my fault for not reading email carefully enough. I am a Debian Developer and will sponsor this request. Fill out the information "Information guest needs to supply to sponsoring DD" and I will sign it.

I do not know which approach is easier. People who work on the Go computer language use this. http://osuosl.org/services/powerdev/request_hosting/
