Without wishing to give too much away, I know a group of people who work at a public transport agency in the UK. They recently had a meeting with Google about "opening up our data" which amounted to Google wanting the agency to sign a contract that would give Google exclusive rights to realtime and scheduling data in perpetuity, then Google would decide if/when/how it would be made public. The agency didn't say "fuck off", but something to that effect.

Now, instead, they're working with a group of students to create a public API with a permissable licence and a framework for other agencies to do the same.

So... maybe do hold your breath? Transit is one of those areas that attracts nerds and nerds love open source.
