Maybe you should re-read the referenced articles that are involved with this story. A special chip
IS required if third-parties want their headphones to
CONTROL the new iPod shuffle.
Third-parties can either reverse engineer the Apple chip (which may subject them to legal action) and build their own or license the chip directly from Apple via the Made for iPod program.
Either way, a new control chip is required and it's going to end up costing us (as consumers) more money in the form of more expensive headphones.
"iPod-accessory vendors V-moda and Scosche, as well as other vendors speaking to Macworld anonymously, have
confirmed these reports, though calling the circuitry a
control chip rather than an authentication chip. As with Apples dock connector andmore recentlyproprietary circuitry necessary for iPods to output video signals to third-party accessories,
Apple will charge vendors a fee, via the Made for iPod program, to include this new control chip in headphones and other accessories.
In the past, vendors have told Macworld that such fees are passed on to consumers in the form of higher prices for iPod-compatible versions of common accessories."
