I think he's looking to run ARM code on an ARM processor. Don't forget there's the "other win32 platform" -- Windows Mobile. This would definitely require forking a new project aimed at that platform. I'm not sure what the implications would be for Android, but I'm sure some of the difficulties would include: - No X11 (as mentioned, and Wine currently translates Windows calls to X11) - Although both platforms (WinMo and Android) currently run on the same architecture (ARM)
