PAN with Linux, iOS, Bluetooth, Bonjour, GameKit -- Possible?

So I read different takes on this matter (I think I read all the related questions on SO). Can I connect in a PAN - Can I write an app that will connect - my linux machine and my iOS device via bluetooth? Using or not using Bonjour or GameKit.

Few requisites:

1. iOS devices are not jailbro开发者_StackOverflow中文版ken.
2. iOS devices may or may not have the hotspot/tethering feature enabled (which as far as I have gathered is dictated by the Broadband provider -- i.e. if you pay you can tether your connection).
3. iOS can run a custom made app that uses documented APIs.
4. Bluetooth can be activated by hand by the iOS device user.

Thank you very much!

iOS 3.0 provides support for headsets (mono/stereo), networking via the PAN/BNEP protocol and support for "Made for iPhone" devices which require a proprietary Bluetooth protocol. Still, not even basic OBEX support is included (available with any low-price mobile phone), and no API is available to connect to arbitrary Bluetooth devices. It also extents the GameKit API to allow for iOS-to-iOS communication.

Personally, I would instead use wifi + bonjour. Here's a tutorial about implementing it, some of the code can be pretty gross, but once you get the boilerplate out of the way, it "just works", which is always a feel good moment.
