How is there not a need for some sort of DRM or lockdown on the phone in your scenario? If you want to get the important developers (EA for example) over to Maemo, they won't even start to look at your platform unless those kinds of protections are in there. (Believe me, I've tried.) Working in games and iPhone development, I hear so many people telling me that 80-90% of people using their apps have pirated them and they've only made back $20k of the $300,000 they put into developing that game.
