Thou Shalt Not Share
How to Share iTunes in Three Easy Steps:
Step 1: Download Hamachi and create a network.
Step 2. Turn 'Share my music' on in iTunes.
Step 3: Give your friends your network's password.
[UPDATE: A friend of mine called me to the mat on making this post public, since I seem to be encouraging the stealing of intellectual property, which, basically, is what the P2P networks have been rightfully accused of doing. I countered that this sort of "sharing," since it requires giving out your password to your network account, is really no different than giving someone the keys to your house and telling him its okay to drop by when you're not home and borrow some CDs off the shelf. He then countered by pointing out that someone could just set up a server with the music on it, distribute the password willynilly to anyone, and voila, instant Apple-crushing ad hoc P2P. He is right to be skeptical and pessimistic, of course, since essential human nature does not change, even though the technological circumstances do, and people will invariably game the system to steal.]
