I'd thought about building this but threw it out when I figured I couldn't get my various devices to talk through it to Twitter. Computer, sure that's easy: fix your host to api.twitter.com, but fixing all the iPhone apps to point to this service instead of api.twitter.com? Not likely. Unless you harnessed the existing applications then it wouldn't be useful.
