Dave this is my last post on the subject, because I agree, not leading anywhere (because even if we solve the problems of the world none of us has the power to implement them :-) ).

1) I only said that why should the EU change its standard to the one of the US. I never said who should change, you did.

2) I just find that it is a big coincidence that the US and EU versions of the Prontos are compatible with the US and EU versions of the powermids made by X10 in RF and format. I never said a Pronto is the same internally as a powermid, but that the RF part probably comes from the same place. The same way that some equipment not made by Philips use RC5 codes because they by the RC chip from Philips.

3) (my initial point) that RF was subdivided differently around the world long before Prontos, X10 and even cell phones were even a dream, and there might be good reasons other then market protection that makes it so that the same frequency cannot be used in different countries.
