I have one of these, too. Sweet.

I've created a Sourceforge project[1] so I can drive the I2C bus (and
specifically the MCP23017 I/O expander).

No releases yet, and no writeup of the software, but it's been an
interesting exercise.

I'd like to make the library interrupt-driven, but that's not so easy on
Raspbian(!) Linux, so for the moment it detects input (switch) changes
by polling.
