We could test the concept here is this community. I think that we will find the critical mass if we join our efforts and channels together with @Katherine_Scott and @fkromer. I can create you a proof-of-concept up to the raw automatically generated diff list of new URL (projects). At the moment I’m heavily working on another open source projects with quite similar tooling. After that I can create you the PoC in some days in a public repository so that we include all requirements. Since I’m unemployed at the moment I would love to work on that. It could also be supported by the protontypes organisation we are currently starting.
The web technology part that comes with the voting is something I have no clue about but my friends at Woost should be able to provide that in days.
