The rreason they are so very very useful is that several dozen or even hundreds can exist on a single digital pin, and they can be placed any distance away from the processor (within reason) and not suffer any ill effects from the buildup in wire resistance.
So instead of 4 or 5 analog thermistors connected near to the board you can have 100 and never use more than 1 digital pin to do it.
each sensor is individually addressable using its 64bit address

Dunno about the software part of your question. I guess you need to code the 1 wire protocol by hand.

I have a thread running in the software interface section now.
