I won't describe the idea, but obviously we think it's not bad. We're looking for somebody to help us build a demo, and join the team if we get through (and perhaps even if we don't). Writing in Rails, and happy to talk to someone with a different background, but wanting to get into it (or convince us to switch!)

Please email me at markk (at) cantab (dot) net, if you'd like to hear more, or make a suggestion. I'm in London at the moment.
