Yes.

Sure, let's cooperate and talk.

Some not quite so urgent ones - like support for guarantees. I think this can
be worked out as we make progress.

Some of the core functionality might be a limiting factor for the requirements.
Lets agree on the requirements, I think its a great step forward and then
build the core functionality with these requirements in mind.
