Unless I'm missing something this I2C only accesses the control interface of
the camera, not the data from the camera?

There's a lot of detail about how BT works here (in German). If I understand
the schematics, the BT hardware is one of the serial-to-BT adapters, so it's
acting like a point-to-point RS-232 to wireless adapter. One photo shows
three? RCXs, so maybe they modified the code in the BT adapter to allow using
more than 2 nodes with the serial BT adapter?
