The url below points to a new Web page I've created called 'HDMI CEC Guide' that will cover all things HDMI-CEC related. The 'HDMI CEC Guide' page is not about our CEC software but will be focused on universally useful bits of information to do with HDMI-CEC in general. I'm still dumping my scribbled notes into the page so expect it to grow considerably as I do that (I have far more scribbled notes than even I expected!).http://www.ellipticalcurve.com/dianemo-products-services/hdmi-cec-guide/
Please take a look at the page if you are into HDMI-CEC or related stuff. I hope you find it useful.
All the best
PS If you spot any mistakes or have something you think I should add let me know. Likewise contact me if you have HDMI-CEC related questions that are not answered by the 'HDMI CEC Guide'
