Outside-in development with Ubuntu

This is a demo of how I’d like to be able to do Behaviour-driven development (from the outside-in) on Ubuntu using stories and automated testing. The story-part is already possible with cucumber – but it’d be nice to be able to use Python right? And the automated testing would use the new notification system in Ubuntu Jaunty (in the way that growl + rspactor is used on the mac) – AFAICS this should be possible already, we just need easy configuration etc.
