The webtop thing runs firefox and a WM, which might well mean it runs on X. It also runs android apps. I wonder if it would be possible to take that android over X thing for the N900 so we can run android apps?
It's probably a very long shot. If it's binary only are cortex A8 and A9 compatible? (I'd have thought they are but am not sure) Here's hoping some kind of easydebian/preenv type affair will be possible.
