iPod Accessories From Apple?

Since the introduction of the iPod, add-ons for the iPod have been the realm of third party product developers only, but now Apple may be looking to broaden the scope of what it can offer. According to AppleInsider, Apple is now looking for hardware engineers to develop its own line of iPod accessories. Last month a job listing was posted for engineering WiFi & video integration into the iPod. It's unclear whether this is related to that position, or if it is a different position entirely, or simply just looking for an in-house liason between Apple and third party developers.
