If I setup password-less login to the cygwin ssh server, using 
authorized-keys, I can access all remote shares from cygwin,
and also from cmd, started from cygwin with `winpty cmd`, for that matter.
Possibly, if the remote login is the first login of the user, the mounts 
will just have to be established? (Using `net use`)
