Norwegian programmer Jon Lech Johansen has decrypted and published the key that Apples wireless hi-fi bridge, Airport Express, uses to protect music streams. Hes also released the source code to a small Windows command-line tool he calls JustePort. In essence his crack opens the door for other applications to broadcast music to your hi-fi over a home WLAN network using Express, rather than just iTunes 4.6. For users on Linux machines, or with WMA or OGG format files, this could be a boon, as iTunes supports neither format out of the box.
Apple is unlikely to look upon it so charitably. JusteForte is the third in a series of endeavors by the Mac-using Norwegian to enjoy Apples services. Johansen has stressed that the tools simply restore rights that Apple and the recording industry giants removed when they devised iTunes Music Store. He has consistently warned citizens against accepting DRM music, as it obliges the user to enter into a contract in which the terms may change at any time.
