Does this support extending GPIO's via a MCP23017 chip?

Nope, but I'm ordering one now!

The library is designed using interfaces so I should be able to implement the same functionality over the i2c bus rather than the sysfs GPIO driver.

Andrew,
That would be great! I currently use exec() to control the GPIO's on 4 MCP23017 using wiringpi's gpio command to control a 64 cue fireworks launcher : )
