The latest update of the Arduino-OWI (One-Wire Interface) library contains additional support for slave devices. The examples includes an emulation of the DS18B20 and a Remote Arduino with the core functions (e.g. pinMode, digitalRead, digitalWrite, analogRead, somewhat like Firmata but using 1-Wire).
