We think it would be neat to do this sort of thing with existing numbers, too. That's why we released Ameche a couple of months ago. http://voxeolabs.com/ameche/overview/

Built by the same folks as Tropo was, so the couple hundred thousand Tropo developers will find the Ameche API familiar.

As it gains carrier support, you'll be able to do all this with your existing mobile number.
