Assuming Canonical's approach to revenue sharing with Banshee is typical of how they approach ISV's with regard to revenue sharing generally..this is not a good sign for their pay-to-place partner repository effort associated with their software center to turn Ubuntu into a platform. Any ISV that wants to sustain their own development of their application with micropayments or subscription revenue from Ubuntu users is going to be hardpressed to find terms such as 75% revenue to Canonical a workable revenue-sharing relationship. That's a really big problem. I don't see how Canonical's Software Center will turn into a vibrant AppStore-like marketplace with such heavy taxation in place for ISVs. It's crippling business model.
