You can't take existing GPL code and distribute it with an MIT license, indeed. But you can distribute the code *you* write with an MIT license. You have to use a license that's compatible with the GPL not because it's a mere derivative of GPL'd code, but because that code can only work by linking with GPL'd code. IIUC this is a theory that hasn't been tested in court. Stefan
