Crunchbutton (.com) started as something similar (originally called "One Button Wenzel", named after a sandwich famous on Yale campus). It's an interesting idea, and might be particularly suited to orders like pizza, which are predictable and repeatable. Unfortunately in crunchbutton's case, the novelty wore off pretty quickly. I'm surprised to see that they're still around, given how few locations they serve.
