Jason put the windows only release of the MUTE program up on source forge today. Source code is there and the release/debug executables.. please spread the word for people to try this one out. It has a few more enhancements than what was previously available. Also, if you are a developer, please take the code and expand on it to get this program growing... somebody could port it to wxWindows, that would be a good start..
You can get it here:
