I was very intrigued by that possibility, but it seems like the stack there is inverted from what it sounds like at first glance. It's for supporting HID devices that are connected to an I²C interface on the motherboard chipset without having to write any kernel-mode drivers. Think stuff like custom lighting or other devices built in to your system that don't need the speed to take up a whole USB endpoint.

I think if someone wanted to have a very simple interface to control I²C devices over USB, it looks like there's plenty of cheap chips around that expose an I²C bus as a simple USB serial port to your computer.
