Wait a minute... didn't dnet fix their keyservers to turn away client versions that would process the invalid stubs? I know they fixed the pproxies, so it would make sense that they fixed their own keyservers, as well. So, unless those people out there that had the old client versions picked up enough OGR stubs to last more than two months in their original grab, it's doubtful that there are too many out there.
I guess a good way to tell if dnet fixed their keyservers is to see how well the PHF adjusted once OGR started. Did anyone here have their PHF blocks stop once OGR started, and then start up again a week or so afterward?
