Now it says it gets rid of the option in iTunes, but that doesnt necessarily mean that the streamripper type applications wont work. The computer still needs to send out the information to the local networks (subnets), so that means that the protocol is still the same, just iTunes can't access it from distant sources (I asume iTunes will be able to "see" any librarys through rendevouz or on the same IP). If you are using the sharing feature as a P2P with a third party program, I dont believe you would be effected. I'm not positive about this however... Maybe someone can check?
