D-Link had a USB Radio with software to do this a long time ago. It may not have been quite as nice, but it could have been and the software just recorded what came into line-in so any external cabling could fix that.
Windows Shared Access is really nice. There is a third-party app that does similar things. It's called DeepFreeze by Faronics. Very cool program. No matter what they do it will be gone the next day. Very cool stuff.
You may still want to apply the security measures others have suggested, but without something like Shared Access or DeepFreeze it will be broken indefinitely until you fix it.
