I lack the bandwidth to respond at any technical depth, but I’d like to make encouraging noises. If you can figure out a way to make GHC do these things without making the compiler terribly complicated and making maintaining it harder, then I’m open to your proposals.

I think most of the communication code could go into a separate executable that can be built by the user for the target-specific communication. The GHC API facing part of the implementation in GHCJS is under 300 lines and that includes some non-exported code duplicated from GHC, so I'm reasonably optimistic that it can be done without too much impact.

Unfortunately I won't have much time in the near future, since a GHCJS release is well overdue (mostly because I keep adding features like this...) and I want to focus on that first, but getting it ready before 7.10 should be doable (especially if other people want to help!)
