Out of curiosity, why anyone would want to port "android" to N900, more than it's ported already? It's system much inferior to even Maemo, not to mention any Mer things, or efforts to update Maemo (CSSU, or rebasing Maemo on upstream debian).

If willing to help, maybe it's better idea to focus on one of above projects? Android on N900 wasn't updated since ages, and due to the way android is heading, it doesn't seem that more recent android versions are feasible for anything.
