If you love the idea and want to contribute, we're totally open source and transparent with regard to roadmap. On GitHub as @teawithstrangers, and more background and info is at http://making.teawithstrangers.com
This is a terrific idea. Out of curiosity, are you a company, a non-profit, a group of people doing a project for fun, or what?
The latter :) We've considered becoming a 501 or something but for now we are just playing it by ear and doing what we can to bring tea time to as many people as possible.
