Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Bluetooth Hardware
With iOS 8 etc now pushing Bluetooth midi and the apps that support this the Apollo series , Midi LE etc. Is any hardware available yet that takes advantage of this by adding Bluetooth built into the controller?
Does it work for multiply devices over different midi channels if so and the latency is low enough this seems like a ideal opportunity for manufactures to start adding Bluetooth as well as a wired connection to their controllers for due use. Will the idea take off seems like a marriage made in heaven and a game changer to me.
