There's some nice information about AirGroup domains and clusters, but little on practical deployment cases. Here's one that others may have.
Multiple controllers, master and some number of locals.
Same vlans on all controllers, but set of vlans in use (per ap-group/vap) unique to each.
No AirGroup sharing expected between any two controllers.
The question is, can I leverage domains (unique domain per controller) to isolate the mDNS queries/responses to a single controller and thereby reduce the overable bonjour traffic?
Does this increase my overall AirGroups limits, or does the fact that all vlans terminate on each controller negate that?

Airgroup domains are a way to allow multiple controllers to share the same airgroup information without having to necessarily trunk all VLANs to all controllers. You cannot circumvent the platform limits listed here: http://www.arubanetworks.com/techdocs/ArubaOS_6.4.
If your controllers do not share VLANS, they will not share any airgroup information. Typically you only want to present Airgroup devices when your users are near to them. 90% of administrators can accomplish that simply by using Autoassociation: http://community.arubanetworks.com/t5/Controller-B
