That presentation will be useful for all who’d like to understand what kind of wireless devices can be used in the home automation system and how. I like it but the CoCo devices, which use some proprietary protocol instead of some standard one, should be definitely replaced by something with support Z-Wave or ZigBee. Moreover, it’s supposed that CoCo devices will control via remote control and not via PC or controller (correct me if I wrong). I found the PC interface but it’s used to set timers and not for integration with home automation system. As a simple and basic solution without controller or PC with specific software CoCo might be good (depends of the price, of couse). But for something serious it’d be better to use devices which support some standard protocol such X10, Z-Wave, ZigBee etc and which can be easily integrated with opensource or commertial software.
