| | NXT to NXT communication?

| Hi all you M[U|D]Ps I know most of the MDPs probably only have 1 NXT, but I'm hoping someone out there has 2, and has investigated NXT-NXT communication. Is it possible? How hard is it? I'm currently thinking Bluetooth, but is there any other way? (...) (19 years ago, 2-May-06, to lugnet.robotics)
