Don't use adobe products here so can't confirm.
It's not all that surprising these days to hear about software companies having their software "phone home" in some manner or another, though it's often quite annoying. However, it looks like Adobe has taken this to a new level. As highlighted by Valleywag, Adobe's CS3 design software includes a system to provide your usage data quietly to a "behavioral analytics" firm named Omniture.
Of course, it does this without ever asking you if you want some random company knowing every time you use this piece of software. While it may not be doing anything nefarious, this certainly has all the hallmarks of spyware, including the fact that it tries to (weakly) disguise the connection to Omniture by making it look like it's simply pinging your local network.
It's really amazing that companies keep doing this type of thing thinking that people won't catch on. There may be plenty of legitimate reasons for tracking the usage of a piece of software -- but if so, why not be upfront about it and let the user of the software opt-in to sharing his or her data? Yet another reason to use a firewall that catches these sorts of sneaky outbound connections
