Rick and Brett,
I just spoke with Marek and Martin this morning, and they will be putting some more thought into a description of their part of the project in the next few days. IN the meantime, however, it's a go, and I'm ccing them on this email. You should feel free to contact them directly with questions, but I'm also hoping that the conversations can be copied to everyone, in general.
In the meantime, I'm very excited about this project for all sorts of reasons. Thank you one and all and looking forward.
