Thank you for your contribution.  It is large enough to require legal
paperwork; I can send you the forms off-list if you agree.

As for the patch: why does this have to be an external program?  Can't
Emacs itself do this job?  Doing part of Emacs's keyboard input in a
separate process has several downsides, so I think it should be
avoided if possible.

Also, did you try this with the latest Emacs sources?  The way
keyboard input works in Emacs on Windows has changed several months
ago.

Finally, will this also work in the console (a.k.a. "TTY") session, or
just in GUI sessions?
