Check out the "TeensyPi Networked Temperature Controller" thread for the hardware/software being developed.
An alternate approach is to use USB to I2C adapters that are not that expensive, and I2C digital and analog hobby boards are not expensive either. I have built a test platform with off the shelf parts and borrowed parts of the automated system software to build a C# app to make them work.
If all else fails then an off the shelf interface like the LabJack hardware is a good place to start, simple to use and has software support.

Any chance you could link to the code?

About the only code from the test application that might be useful is the IOworker and Controlworker classes, the rest is graphic related. This is only useful if you are using a http://www.gravitech.us/i2c16gpex.html GPIO board and a http://www.gravitech.us/i2c128anco.html analog IO board. This is not a ready to run brewing application, just something I created to test a few ideas and boards in preparation for a more complicated control board design that overcomes most of the IO noise vulnerability and output current limitations in other systems.
