Theres enough information from the discussion to begin moving forward with coding. Andrew Riedi and I thus far are the volunteers to begin digging in. If anybody else is interested in getting their hands dirty please do respond to this, and we'll work out how to get it done. I imagine I'll setup and email a public .git (that isn't live to winehq) for development. Stay tuned for that.
I can offer assistance with the general appdb design, db questions etc. I'm glad to see that someone is going to pick this stuff up, the appdb could be much better than it is and its a great tool for wine users.
