For Xeroxs (XRX) Kevin Walsh, 10/1, as he calls this past Tuesday, was years in the making. Walsh is the managing director of a division of Xerox thats working with states on the insurance exchanges created by the Affordable Care Act, and Oct. 1 was the day all of them went live. I checked in with him to see how the first few days of the exchange went in Nevada, where the company both runs the technology that underpins the website and operates the call centers that field queries from the public.
