Meeting the team at the conference seems like a great opportunity but I'm wondering whether this will be an effective way to get a collaboration started or learn how to participate in their efforts (as it would require a 20 hour trip from Berlin for me).
For me, the biggest questions right now are:
* How are they going to organize their work?
* What kind of contributions are they looking for?
I think it would be great to address these things at the conference.
