I’m not sure how much I can actually contribute to this, but I’ll just add a few pointers to nothing gets lost. I’m not very familiar with remote ghci, but I think that there is some overlap between remote ghci and out of process template haskell compilation[1][2]. Most of ghcjs’s TH code is in src/Gen2/TH.hs.
To be honest, I haven’t had much time last year to do anything for the out of process th stuff. I’m planing to get back at oopth, once we got shaking-up-ghc[3] to build cross compilers properly. From the looks of it, that could be soon :) I only know about the ghcjs repl[4] through twitter. I’m certain luite can share a lot more here. With respect to remote ghci, I haven’t had much time to look into it. The main focus of out of process th (for me) was getting TH to work for cross compiler, which means shipping code to a remote process through some kind of channel that the remote allows*. Hope this might help in some way.
