Apple has put DRM the headsets of the iPod Shuffle ?

Here is a subject which will restart the flow of polemics about certain procedures of Apple. According to iLounge, who have tested the last iPod Shuffle in great depth, Apple has locked the operation of the walkman so that it cannot function with other accessories than those which will be authorized. Thus, any headphone set intended for the iPhones or iPod and fitted with a remote control will not be recognized by the walkman and will not start the iPod unless the headphones are fitted with an Apple "authentication chip".
The EFF follows along the iLounge path and is very critical of this behavior, stating that Apple adds DRM everywhere where they it can, in order to block the manufacturers of compatible accessories unless they pay royalties to Apple.
The story above is possible, and it would not be surprising for Apple. However, there remains also possible that the communication between the walkman and its remote control is a completely updated process what would explain this incompatibility. Ilounge detected at the time of the test of a noncompatible headset of specific whistles at the limit of the audible seeming to be an attempt at communication between the iPod and its remote control. Apple perhaps decided to use an analogical management with a numerical system, which would not be astonishing knowing the number of possible actions with these 3 buttons,namely: the pause, the change of list of reading, the reading of the title in progress….
Note that if this system is practical, it obliges a user of Apple product to dig into in the instructions of the iPod to be able to extract the maximum from it.
