It would be a device that plugs into your car's onboard computer. There are dozens of devices out there that do things on the hardware side that are very similar to what I'm looking for, but just not exactly. I don't think I'm going to get very far asking them to change their products either, since the changes I'd be asking for are too specific to what I want to do.

Does that help you point me in the right direction? It doesn't seem like an overwhelming project for anyone, but none the less, someone would need to dedicate themselves to getting it built, and I just don't know how to find that person.

I also have the chicken/egg scenario here where I'd love to get funding for it, but need to partner up with someone on the hardware side to at least get it to the prototype stage.
