That's exactly what we're doing at http://www.plugshare.com. Check it out. The blue icons are residential charging stations and the green icons are public charging stations. Over 2,000 people have signed up to share their home electricity with EV drivers in need of a charge.
I like your site but I would love to also use your site as a reference point for setting up my own station. I imagine you can monetize this lead generation process in some way as well.
