ReST interface for wordpress

We had a need for some restful loading and access to wordpress posts data for a project at University of Cambridge so we created a simple rest interface. I was thinking this kind of thing might either already exist or be useful to the entire community if I extended it a bit and submitted a patch. I guess this is really a 2-part question.

1) Is there a ReST interface for wordpress somewhere already (or is someone working on one?)

2) If not, where is the right place to submit a patch to add one (or maybe where is the right place to discuss what the patch should look like?)

Thanks
