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.

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.

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 ?
