Cameron quickly followed up with a Dabble application to do something similar.
I think there is a need for such "match-up services". Students and postdocs who feel strongly about sharing their research openly would certainly prefer working in laboratories where that type of thing is tolerated, if not outrightly encouraged or required.
Similarly, PI's who feel strongly about Open Science would be thrilled to find students and postdocs sharing their mindset.
Check out (and contribute) to the Nodalpoint and Dabble initiatives if you can.
