“Eclecticism, (from Greek eklektikos, “selective”), in philosophy and theology, the practice of selecting doctrines from different systems of thought without adopting the whole parent system for each doctrine.” – Encyclopaedia Britannica.
I think you should consider moving the source code of the Snappy Driver Installer to Github, so it could get more contributors as there are many users that can help with the project and effective issue reporting etc. Github would be the better source code hosting option IMO.
I would also in addition to above suggest moving driver database also to Github, It will allow for incremental addition to database to get update reducing update size. Also Community will be able to help increase the Database substantially. It would iron out the process of adding drivers repository not currently included.
