Two problems there: First, sending back the UDID is a violation of the new developer terms from Apple.
Second, thats not how apps are supposed to work on the App Store. When the user buys an app, they expect it to work on all of their devices that are synced with their iTunes account. For example, I have an iPod Touch, an iPhone and and iPad. Not only would I be angry as a user because your app only worked on the first device I synced with, but there would be no way for me to even buy a second copy of the app for another device on my account. I'd guess you'd start racking up nasty reviews and Apple would pull your app for that. The bottom line is there there is no way for you to "know" what devices actually belong to the user, and stuff from the iTunes store is expected to work on up to 5 machines on the same account and all the devices synced with those machines. That's what Apple tells users to expect. Again, the real piracy problem isn't machine sharing, it's jailbroken phones running pirate copies downloaded from warez sites.
