We've done some experimentation in roughly the same config, though it
was 4 channels at 512kbps each (plus audio), over 802.11a/g. One good
thing we did was to disable the lowest connection rates across all
protocols.
In our test it wasn't so much a function as number of users, as all 4
channels were essentially broadcast (first generation lightweight APs ..
multicast is effectively broadcast). Recently lightweight models for
multicast are much better at controlling traffic, but at 2Mbps I doubt
you could get too many channels going without affecting the data
traffic. Better QoS controls could help though.
So I'd say it's good for the press release but at a decent resolution
it's going to be difficult to support more than a few channels.

I know Dartmouth is doing this on their campus. Using 802.11a radios for
this purpose.

We actually have the same Video Furnace IP TV system as Dartmouth and
we currently provide over 20 channels to our dormitories. Each channel
is currently a 2 Mbps stream.
I am starting to test the system over the wireless network. I wanted to
see if other schools had done similar testing yet.
The first question I am trying to answer is how many users per AP?
The second is will this work with 802.11g (not allowing 802.11b
speeds). As most of our users still have 802.11b/g radios?
The third is what is the implications of adding wireless VOIP sometime
soon?
Our current infrastructure is Cisco 1200's using a WLSM/WLSE solution.
I hope to start migrating to a controller based system next summer/fall.
