Wow, amazing, a simple hack and you can authorize iTunes on eleventy billion computers.

Authorize your iTunes library on more than 5 computers - Lifehacker

iTunes stores authorization info in a hidden folder (/Users/Shared/SC on Macs, C: \Documents and Settings\All Users\Application Data\Apple Computer\iTunes\SC Info on Windows). On an authorized computer, back up the SC Info folder, de-authorize the computer, then restore the original SC Info folder. Your computer should work as though it's authorized, but will no longer take up an authorization slot in iTunes.

So, how long do you thing this will be around ?
I assume Apple will fix this soon.

From the article:

"Just so you're aware, there is a gotcha. If you follow this method, you won't be able to listen to music you've purchased after the authorization trick, since iTunes changes the key each time you download a new song (apparently it still works with your old purchases)."

It's not the magic wand it looks like. As the linked article points out, this will only work to allow the hacked computer to play songs you already have-no new songs will work on the hacked computer.

With that said, I think there will indeed be a patch for this soon. It's a silly thing to broadcast, but it is a cheat nonetheless.

Not a great trick but it's good to know.
