Bluetooth iPhone accessories

Since OS 3.0 came through, one of the key features I was expecting was the ability to connect the iPhone/iPod TOuch to external local devices and use it as a stylish sexy controller. Yet, once again, it seems that Apple is failing on adding properly a new feature to his OS (follow my eyes, think Push notifications, copy/paste…).
I’ve been looking for the appropriate API entry points for months and yet apart from the unclead EAAccessory class and the Peer-to-Peer bluetooth gaming feature, nothing has shown up. Even more after digging the question it seems that the iPhone BT stack implementation is reduced to the absolute minimum.
A project, btstack, has been started to fill in this need, but it seems that this only work on jailbroken phones…
Yet who wouldn’t want to see this kind of apps pop in on the iPhone ?
This means that BT accessories will have to be made specially for the iPhone using probably CSR’s dev kit announced a few days ago. So new devices will probably start to pop up in the next 6 to 9 months, but let’s be honest, do I need to change my gadgets AGAIN to have them supported by the iPhone now ? This sounds like a bad joke…
