TfL mashup idea

While looking for ideas for topics at Be2camp, I came across another cool suggestion on Show Us a Better Way, the UK Cabinet Office’s Web 2.0 competition site for ideas to unlock the potential of publicly-held information (see posts here and here). James O’Malley has suggested opening up Transport for London (TfL) data and making it available to mashup with Google Maps, mobile phones, etc. As an Oyster Card user, I also really like the suggestion of linking it to location tools like Yahoo Fire Eagle.
