USB controller MIDI over Bluetooth?

[celebutante]

Here's what I'm trying to do: I want to use a small USB controller (like a Korg nano) wirelessly. Is it possible to plug its USB out into an iPhone/iPad using the camera connection kit then transmit via Bluetooth to a Mac laptop?

It appears that something like the iOS app MidiTouch would let you do this, but it's not clear whether it supports external hardware controllers.

Any help would be appreciated.
