I'm super happy to see everyone is so positive about the plan, and
thanks to all for the feedback. This response is an indicator (and a
lesson, at least to me) that the change was overdue :)

This new setup will  let us all work with better integration towards a
common goal.  I have urgent, immediate need of the ip1  features being
usable in production for research work at Berkeley, and I also want
things to be in good shape by the end of the summer: in the fall new
grad students arrive, and there are a number of interesting research
ideas that Brian and I want to push forward with that will require a
workable codebase for others to participate with.

Having the support of bzr will hopefully allow us to be flexible about
trying out small experimental side branches for new features with
regular merges, instead of the 'forever split' situation we were
trapped in.

So let's move on!
