Can you pair more than one wireless keyboard (AWK, I would need 3-4) with the same ipad? Not to be used at the same time, but to say have a keyboard in different rooms and being able to use them individually with the same ipad.

Welcome to the forum! The iPad can only recognize one BT keyboard at a time so my only concern would be conflicts. If the rooms are far enough apart and/or you have the BT keyboards you're not using turned off, your iPad shouldn't have any problem recognizing each keyboard that you pair it with. However each time you use a new keyboard it may need to be re-paired.

It's an interesting idea. Let us know how it goes!
