I'm on windows too, you can do these things.
First, getting OpenSSH on the phone is threw installer, but its possible you already have it. Look in the installer "All Packages" and look for OpenSSH, it its not there, you probably have it. Install something like BossPrefs and see if the slider for SSH is there/slide-able...
Once you have OpenSSH running on the phone, get this program

when you get it running on Windows give it your phones IP and wait a bit, it takes a while for the encryption keys to be built the first time. You should be then logged in. From there you can do the steps above, (rightclicking on a file to change permissions). You can issue command threw it too like 'chown' to change ownership but I'm not sure you will need to do that for smsnotify.
Later on, you can install putty , then you can SSH into the phone from windows directly, (both programs are very useful for iphoning)
