Show HN: GitHub Based Accommodation

Hi all, A few years ago, I wanted to have other interesting people stay over in our spare room. To invite Hackers/doers/makers/conference speakers, there is no "interesting" filter on Airbnb. So I created a hack, https://www.gitsurf.com/ https://www.gitsurf.com/, based entirely on Github, which has a very high barrier to entry. https://www.gitsurf.com/pages/man https://www.gitsurf.com/pages/man has more information on the mechanics. Would people here use it? Should it be entirely open sourced?
