This project is _not_ about bringing UNIX to Windows. It is about bringing the open ssh protocol to Windows. As a daily UNIX and Windows user in an enterprise environment, I can say that a fully integrated sshd is a welcomed addition. I have written and maintained many WinRM interop ruby gems and cannot wait until we can deprecate them in favor of a better and sane remote she'll implementation. This is a real milestone, keep up the great work.<p>As for Cygwin sshd, it does work if posix is the order of the day but if you need a reliable terminal (for things like powershell) that scales to hundreds of servers and many admins Cygwin simply fails the test. Clunky domain authentication, private key auth is a joke, powershell only works sometimes (thanks PTY), network tokens are non-existent, etc. the list goes on and on.
