Is that documented somewhere? The "contributing" link in the readme also 404s. I would definitely need to understand the licensing and how contributing works before I could consider integrating this (and I would definitely consider it!). Cool stuff.
Just for future reference - if no license is given it's unlicensed. Licensing defaults closed for extremely good reasons - that's one of the reasons why github had a strong push for users to assign appropriate licensing documents to repositories a while back and declare those licenses in machine readable forms (if applicable).
