Interfacing to 1-Wire LAN, especially Dallas temperature sensors?

[Christian Aastorp]

I'm considering doing some temperature control and logging, both
enviromental and inside computers. Did a google search, and found
references to the range of temperature sensors from Dallas
Semiconductors. 

I also found schematics for interfacing with the serial port, and
timing diagrams for implementing 1-Wire Lan using direct control of
the port.

As I'm using  Python for my programming, these days, I would like some
pointers to modules or techniques to use Python to read the
temperature sensors.
