there's a "non-free" section in the maemo.org repositories, if you have implemented a payment infrastructure yourself, you could upload it there. in the meantime, you might want to read these two threads about selling commercial applications through ovi store: http://talk.maemo.org/showthread.php?t=34661 http://talk.maemo.org/showthread.php?t=34783 some of the facts discussed there might be subject to change, as the new Ovi paid app system for Maemo still isn't ready and implemented yet.
