server rake task provides no way to override listening interface

[technomancy]

Running "rake server" always listens on localhost no matter what. It would be convenient to allow it to bind to another interface.

Could you be more specific?

[technomancy]

I've got an appengine project that's just a web service for an android app. My emulator can't reach the development server launched by rake server since it's listening on 127.0.0.1 instead of 0.0.0.0, so it would be nice to be able to override that when desired. I could probably put together a patch for this; (maybe triggered by an environment varibale?) I just wanted to make sure it's tracked.
