I'm not interested in the gig, but if you look here
it seems as though all you have to do is give each data source a unique resource name. In the case of this example, there are three "temp", "onoff", and "1". In your case, you would have a "temp1" and "temp2" and so on.
One wire is a bus. Each device has a unique ID code. Wire the temperature sensors or other 1-wire devices in parallel. No additional pull-up resistor required.
What you are asking for is more than a $10 effort unless you already have an equivalent system set up and I don't.
