Brainstorming?

O.k., let's have a look at unused possibilities of my nodes:
- audio
- IrDA
- I2C
- 1-wire

To be serious (and more on topic;-), for 1-wire I will try to develop 
failover. A 1-wire bus can only have one master, and if the node dies, 
somebody has to connect the cables to another node. But have a second 
master in passive "listening" mode, and switch it to active mode at 
failover, should work from theory.
