I'd like to see a mobile-sig, because I think there's enough to discuss that isn't relevant to -dev. I plan to get IronPython running on Xamarin Android/iOS sometime this year so it would be helpful to coordinate things with CPython and Jython - for example, what the values will be for things like sys.platform and os.name will be, and issues around file system emulation, supported modules, etc. that should be compatible for all implementations.
Plus there's the issue of new libraries for sensors, GPS, cameras, etc. that provide Pythonic wrappers over the platform APIs. It's not just "get CPython working on mobile" but "how should Python look & feel on mobile devices". (Of course, CPython is special so it's implementation details are still fair game.)
So +1 on mobile-sig from me. I'll even volunteer to get it set up & administer it
