I've looked at this for a while. I made a post HERE
at BC with some info. I was looking with some friends as an investment op,the carrier,chip and modem mfr's. It still doesn't address the interference drawback. It's bandwith is all over HAM radio. Also I remember something about the radio waves (as that's what it is) bouncing all around the world and possible major interference from this. The interference is (noise,I believe) pollution. SeeTHIS
part of earlier link. Unless they address this interference, I feel they're going to have trouble with it. It has it's good points and is an excellent technology. It will be cheaper to operate most of the equipment already exists. Maybe with Google and IBM pumping $$ into it it will be worked out. I have faith in it aside from my concerns. And it was a reason why we purchased some goog stock ad a few others we hope will take off. I have most of my faith in Yankee ingenuity. We rated it with early MSFT and Apple's intro of the IPOD.
