Good questions. I believe the current effort referenced by the blueprint
is focusing on moving existing code into the incubator for reuse, to make
it easier to restructure later. Alexei, do I have that correct?

I was starting to feel like an (unnecessary) bottleneck, so my goal for
this email thread was to step out of the middle of the conversation, and
make sure everyone who is doing the work knows about each other so you can
all coordinate directly.

If we need more details for requirements and a design, let's start writing
them up. Maybe a wiki page or etherpad to get started, and turn that into
blueprints when ready? Who wants to take that on?
