I am considering building an all-1-wire system and am wondering if someone can point me to any 1-wire devices that can be used as addressable switches to toggle 5V on or off? 

(yes, I know it would be trivial to have arduino toggle its' outputs.......)

Maxim bought Dallas Semiconductor so they own the 1-Wire name.  http://www.maximintegrated.com/products/1-wire/

It looks like there is no 1-Wire output device.

1-Wire Devices 
Memory: EPROM, EEPROM, ROM (22)
Temperature Sensors and Temperature Switches (10)
1-Wire Interface Products (6)
Timekeeping and Real-Time Clocks (1)
Battery Protectors, Selectors, and Monitors (10)

Sure, but other manufactures make devices as well.  Could a PIO device do the job?

Take a look at the DS2406 and DS2408.

PapaG, thanks, I took a look, it looks fairly complex to use those to just pin a high or low value to the PIO outputs?

If 1-Wire is too complex, then perhaps you should consider not using it.

In theory there is no difference between theory and practice, however in practice there are many...

Is I2C not an option? not exactly 1 wire but I2C can control up to 127 modules each of them controlling 8 relays.

what is the distance between controller and the relays?  thinking rs485 ?
