Normally, to get something working that has been a long-term stumbling block, one would initiate a brainstorm, rather than a dicussion thread (or I would anyway). However, there seems to be a separate community in parallel with maemo.org so perhaps that's the place to raise this?

On the other hand, the absence of a fully operational connections (as per functionalities on nitdroid-N900 page) is probably the reason many would give for not installing nitdroid (out of those who don't have nitdroid installed). Therfore, you could try brainstorming on TMO and see how far you get. It is possible that something will emerge that hasn't been tried or considered by the nitdroid team?

Lastly, the phone and camera are known to be in development and the nitdroid team are clearly very competent programmers so let's just wait and see what they come up with.
