[Feature Suggestion: External status/control interface]

I submitted this as a suggestion through the ticket system and Brandon responded suggesting I post it in the forum as well:

A feature I think would be nice to have on a future model would be some sort of interface (maybe i2c or spi?) through which one could attach a microcontroller and have it be able to read status data and write setting changes.

My purpose for this would be to be able to create a custom user interface with a different display (specifically in my case I want to build one in to a Gameboy chassis and have it use the Gameboy's display), but depending on what sort of features you might be able to expose it could also enable interested parties to experiment with different power curves, or use your controllers in a scientific setting where a computer could automatically adjust different things for test runs.

It might even be possible to add this to existing models as an option in a firmware update by repurposing the display connection, since presumably the display is using a common serial interface.

I'm curious what ideas others might have for things you could do with the ability to control or pull data from the power controller.  Bluetooth/WiFi data logging for example?
