While not "exactly" what you requested, this may work:

It's a small add-on board that reads four DS18B20 sensors, does all the nasty decoding, and provides a simple text file with the readings to a serial port (USB). This can handle 30' cable lengths and other versions have up to 8 sensors. Cost is around $40 with four sensors.

I'm using this with a Raspberry Pi to do logging at my cottage, then use a windows PC to grab the data and further massage it. Future plans are to use the Raspberry to control the boiler...

I've already "rolled my own", reading the DS sensors with the PI, but this is so, so much easier. Good luck!
