As you might have noticed, there is already a nRepl branch in the repo. However development in that direction stalled due to time limitations on my side. The main reason is - as usual - Windows. I'm looking for a feasible way to get a small, fast client which also works on Windows without further dependencies.
I recently revived my investigations in this direction. I'm looking currently into Haskell and Factor. Both provide self-contained environments for Windows which are able to build native executables. The OCaml client for jark would also be an interesting point, but OCaml does not come with said self-contained environment. You still have to mess around with MingW and/or MSYS.
