Pages and DoubleClick?
I downloaded a trial of iWork '09 from Apple today to check out some of the new stuff. I run a utility called Little Snitch that tells me when apps I'm running make network connections, so I watched Pages's interaction with the outside world the first time I ran it.
When you enable the free trial, it sends your registration information to littlebuddy.apple.com. Nice innocuous sounding name, no?
From there it goes to configuration.apple.com, metrics.apple.com, and then the last one it connected to surprised me: ad.doubleclick.net. DoubleClick is a well-known online advertising company.
It only did the doubleclick connection the first time I ran it, but maybe that's an occasional thing. But I can't think of any reason for Pages to be connecting to DoubleClick.
