--- Comment #10 from Jakub Jelen <jjelen at redhat.com> ---
During last months I devoted some time to solve this problem. In
cooperation with Cygwin maintainer I build ssh client for cygwin, which
is able to connect to server using multiplexed connection. It was
briefly tested in scap-workbench for windows [1] and success was
reported.

It is really unlike that file descriptors passing will be implemented
in cygwin in near future (not sure if windows is even able to do this
somehow) so we have chosen to make workaround in openssh using unix
domain sockets. Unfortunately, it is not full featured solution and it
doesn't handle full featured pseudo terminals. It is targeted more to
remote command execution, file uploads and file downloads, which is
more common use case for automation and works fine.

So enough of words, here is the current version of patch [2]. I'm
posting it here to see if upstream is interested in this feature,
otherwise it will have to be maintained as downstream cygwin patch. And
of course, comments, improvements and patches are welcomed.
