No idea - I was just on the technical execution side of the project in the early phases. Behavioral economics would suggest that opt-in rates are almost always lower than opt-out. http://ozankocak.com/2011/01/18/dan-ariely-and-behavioral-economics-part–i/ . I suspect many tech companies have adopted similar views on opting in or out. Secondly, at a more technical level: In a MDU with a whole bunch of Comcast subscribers, could one router be able to detect existence of strong Xfinity signals and not enable its own ? This would reduce crowding of Wi-Fi spectrum. I take it such a feature would require special rogramming/firmware by modem/router manufacturer ? This is definitely specialized software logic and on the frontier of work called radio resource management. I am sure most WiFi chipsets have simple aspects of this built in but some companies are working on new technology & tools in this area for unlicensed spectrum like WiFi. Jason
