We have a bus system that I love, so "Yes".

The company that runs them tries a sort of service like you've described, but I have anecdotal evidence that the trick is no one wants to drive. Part of it is that they will provide a vehicle and so they want a sole person to be responsible for it, which isn't applicable to y'all. The other thing is that a lot of people are like me: traffic makes me an angry person and I'd much rather play around on my laptop or read than drive.

I don't want to sound like a nay-sayer. I definitely think that there's a market for this. However, I'd expect some strong regional trending (which is to say poor adoption in some cities and awesome adoption in others).
