I've developed the TeensyNet networked 1-wire controller.
The TeensyNet can monitor / control up to 36 1-wire devices, including igital thermometers, switches, thermocouples, etc. Multiple TeensyNets can be connected to your local intranet and monitored / controlled by a web interface.
The hardware and software is entirely open source, so you can modify the TeensyNet system to suit your specific needs.
