I don't have much interest in windows apps, but I wouldn't mind donating a bit of money (as opposed to free time) to the project.

> The biggest issue with winepak, which is why I haven't been working on it, is that it all revolves around me building things instead of a remote server doing it and having people contribute. I really just need to get the buildbot & sdk in a place that it can auto build an push out. Then it can do all the signing and building again and this shouldn't happen. I just need to find the time.
Maybe a few PR around automation, and/or donated CI runtime could help a whole lot?
