Jarance,From the page, what I undestand is that I-bus is a one-wire serial interface connecting one master to multiple slaves. The bus is an open collector where the master pull it up to 12V, any slave who wishes to sent information needs to just pull it down accordingly. That is on the electrical side of it.On data transmission, it is a 9600 baud serial interface so a microcontroller with UART function built-in like PICs would be able to communicate with the bus easily. Bit banging is an option if the microcontroller is fast enough or one need to resort to assembly programming.The slow interface speed explains why my DICE iPod integration may hang sometimes. The master/slave can get confused if too many slaves flooding the wire.Let me know if any of my understanding is off the mark.Thanks
