Yes. As far as I know, ESS sits on top of the "comint" layer, which is
a body of code that is designed to run any stdio program from within
emacs. So you don't just have to clone ESS, but also whatever comint
does on Windows (which is likely nontrivial).

-- or setReader(), except that that doesn't exist in R (yet?). You
*might* be able to fake something like that using fileevents in Tcl,
but don't come to me if you can't get it to work...
