Wow! I've been looking for zibgee interfaces for a while now. Guess it's easier than my trying to build one to interface to the USB port (it's on my to-do list ... Eventually).

What is the data throughput? I2c isn't exactly very high speed.

It's pretty fast, the baud rate between the NXT and NXTBee is at a max of about 115Kbaud. It's half-duplex, of course. While I haven't done any real speed tests with it, you can see what I did with them here: [LINK]. It uses a fairly robust transmission protocol on top of the serial data to ensure that corrupted data can be detected. There is no error correction, only detection. The article has a link to the ROBOTC files and pics of the FSMs.
