This link if for Windows, but it runs on Windows 3.1, so I assume the empeg wont have any trouble with a Linux version.

With *what* Linux version? I don't see the source to the Windows version so I'm guessing a Linux version would have to be written from scratch? Are the specs open?

This sounds like a neat feature (and very wel-suited to the Empeg since it's in the car) but writing something from scratch sounds like a massive project...
