Outstanding Issues

Network information on Windows is incomplete. I haven't used Windows (outside gaming) in many years and unless there's demand for it I likely won't implement this part. Feel free to open a PR or an issue and we can chat. Honestly the only reason there's a Windows binary at all is because 'cargo-dist' made it so easy to do so.
