Over what period of time?

All at once, presumably. Just now (5:45 AM PDT) I looked at Flight
Radar 24 http://www.flightradar24.com/ and saw 4 aircraft near Portland
and 3 near LA.


So much for the assertion that ADS-B is far off into the future.

Don't forget that this is all from aircraft with Mode S/1090ES kit.

Take a look at Flight Radar 24 and point it at Europe or the UK if you
want to see how far the USA has to go in equipment uptake and coverage,
though in fairness, as the site's coverage depends on volunteers
connecting receivers to the 'net it will be deficient in the USA because
there's so far little incentive for plane spotters to install the
receivers.
