I've got no idea how CD-keys get added to the list of bad keys that trigger the piracy protection. But I doubt it's as easy or as automated as "trigger the CD key violation in a mp game and your key gets revoked."

That stops those orders from being used and has been reported here several times but never followed by "and now I can't play at all"

So I wouldn't worry about transferring the game to a different computer, or even installing on another computer for your own use. (The license allows that right? I was using another machine as a server for Dom2 for awhile and playing from my main desktop. I don't think there's a problem with that. Or even having a copy on a laptop, so you can play turns while away from home.)

Now if you give your CD-key away to all your friends and post it on warez sites, that'll get it on the bad list, I'm sure.
