Where can I Buy it?

You can buy some rudimentary software, including source code, and a programmer's manual from Home Automation Systems (http://www.smarthome.com/) . You can get their catalog by sending your full mailing address to catalog@smarthome.com or by calling them at 800-SMART-HOME (800-762-7846).

Here is one part of the puzzle to get you started: Key Codes for the OFA-5, 6 and 8 "Upgradable"'s when controlled from a serial port.
