Yeah, sorry, gazillion SSIDs definitely off the table. AppleTVs are/will be
hardwired on their own vlan, separate from users.
DNS-SD also off the table, since Apple, in the name of DRM, made AirPlay not
work with DNS-SD.
Target audience is high school teachers, few with the slightest technical
comfort level. Teachers bring school issued laptops into classroom as needed,
and the point of the exercise is to make connecting these laptops to projectors
as easy as possible. Laptops are mix of Win/OSX
I don't think Bluetooth would work, but it's a path I hadn't considered.
Oh yeah – Aruba Aps are in tunnel mode, so all ethernet traffic is tunneled
back to the controller, and the location relationship between user and AP can't
be determined from switch port or anything else physical. Aruba does include
the AP name in the radius request packets.
I'm well aware of the joys of mDNS and bonjour when it escapes the homes it was
designed for. I have airplay working across VLANs, but without any real
control. Hence my desire to make PF part of the equation.
I also realize it's unlikely to be practical – I'm pretty sure PF would need to
interact with the Aps directly – I think it's possible, just not for less than
buying Clearpass.

I assume that a gazillion different SSID's (one for each room) is off
the table? I'm also making the assumption that your goal with the
Apple TV's is to use them for wireless video presentations from iPads
or other IOS devices.
mDNS and Bonjour are great protocols for a home network, but obviously
don't scale to enterprise deployments out of the box. I wonder if you
could geofence unicast DNS based on AP, and then place the appropriate
Bonjour records into DNS statically? Utilize the concepts of Google's
8.8.8.8 DNS anycast system on your local network?
Instead of Apple TV's, have you looked at AirServer? The price is
cheaper if you already have a PC hooked up to the projector/TV, and
it may open up an option to set up a Bluetooth IP network so that
the projector traffic can go that path but the rest of the IP
packets from the client(s) go via wifi. As the people building OBD-II
automobile diagnostic dongles discovered, IOS devices can't associate
to more than one SSID at the same time (and it won't use both a cellular
link and wifi at the same time), so you need to use Bluetooth if you
want to talk to a local device and still have Internet access. The
$64,000 question is whether IOS supports a Bluetooth IP network, and
if it also has the same restrictions?????
