I just ran across a guy at my work here for a meeting, with Airbiquity...
Telematics - Mobile Resource Management - Connected Vehicle - Connected Car | Airbiquity
Check them out! would be sweet... Don't really know how to present this, but sounds "BIG". Like not in the DIY section or $ range of most of us, but apparently they do extensive work with android apps, and system integration of the Nissan LEAF and other recent make/models
Just kinda throwin this out there
