Sony AIBO

I have two AIBO's, a black ERS-7 called 'Rakker' and a 'Pug' called 'Pukkie'. Rakker has WLAN, so I can check if he is awake or not. I do this by simply trying to fetch the album html page.
You can also command AIBO to do something by sending him an e-mail, this is not supported yet. It would be even better if AIBO's protocol was known, so we could command him directly via the TCP port like Sony's software does.
