The real question will be in the spectrum usage and policy. Google's pushing for (read: I believe has successfully lobbied for) open standards for wireless Internet connectivity - the big telcos want to be able to lock in their own service and access devices - think Cingular and the iPhone. As far as I know nobody's saying this has to be used for 'net access.
My hopes - abundant cheap high speed Internet everywhere in the US to include portable and handheld devices. Oh yeah!
Lots of talk here - I'll post when something eventful comes out.
