What is the plan for Remus here?

It has pretty large implications for the flow of a migration stream and
therefore on the code in the final two patches, I suspect it will
require high level changes to those functions, so I'm reluctant to spend
a lot of time on them as they are.

"intention"

(please run a spell checker over this document, if it's anything like
the code comments I've seen while reviewing it will be full of spelling
errors).

How confident are you that this can be done before 4.5? I suspect that
it's going to involve an awful lot of replumbing.

I also think it will interact in exciting ways with the remus stuff.

I think we need to start seeing the start of concrete plans for both of
these things ASAP.
