My team (TfL Online) has a hackathon coming up soon based on our new API, it would be good to hear how we can get that out there for the attendees to be aware of?. (I'm sure you are pretty jam packed on the schedule this time round though)
Without giving too much away (I'll get shot by the press team!), its a single API covering all modes of travel in London and surrounding areas, mostly for the first time, think fares, enhanced accessibility options, geodata etc.
Drop me a mail and I'll get you on the invite list if your interested.
