Well, thats what I'm trying to understand.
Ideally I would like the Presenter to register (using Guest Self-Registration) and have reception add them into the Presenter Role. This would give them access to the Guest network (along with everyone else) with the added function of AirPlay.
What I don't understand is how the mapping of the 'Presenter' role matches up to, and validates, the AirGroup shared role (which is owned by the Instant/Controller AirGroup setting).
Does that make sense?
Perhaps someone has a sample config?
