He hasn't. There's no single part of the input stack that is closed, yet for some reason we have to read the "Maemo software copyright".


Preenv requires some work to be able to simulate multitouch. Namely, Palm uses a partially modified SDL with 1.2 and 1.3 bits, while on the N900 we use a pretty much stock SDL 1.2 In order to get multitouch to work Preenv would need to ship its own SDL, based on cleaning the released bits of the Palm's SDL.

This is not very hard but would complicate maintenance quite a bit, and as you can guess, I do not have time to spare .
