Mr Livingood:

Out of curiosity, had Comcast decided to use an "opt-in" instead of "opt-out" method, did your marketing dept have any idea of percentage of customer base who would have opted in ?

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.–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.
