I looked into this for an audio app, and it looked really cool. Then I contacted him to find out what contingencies were in place because of the truck number of 1 (!!). I asked him if he had any business partner, or perhaps a dead man's agreement in place in the license by which if the company folded or he left it would revert to open source. Not only does he not, but he was a jerk about it, completely dismissive of it as a valid concern. No way would I put years of work into a project on a platform that might become stagnant because of his lack of foresight or understanding there. So I just used QT and other audio only toolkits. Pity, it's really neat looking.
