I'm not sure I like hardcoded URL's that fetches stuff every time I run a program without good reason. Also, I wouldn't ever trust the program itself to check its integrity. But I digress, it's definitely an interesting project.
What are the pro's and con's of using it instead of the win32 version of OpenSSH? [0]
