We are currently setting up a pilot with VideoFurnace. We are using LWAP as well, but are not looking to stream over the wireless network for a while. This is partially due to the Cisco CCA application we run to do authentication for our wireless network. As of now multicast does not work over CCA. It is expected to be fixed in the future. I would really hesitate to run this over 802.11b/g access points since all it takes is one b user to drive everyone from 54Mbs to 11Mbs and really clog up the network unless you really limit the bandwidth you set up when you encode. 802.11a is a much better choice. I think that Dartmouth has totally replaced their wireless infrastructure with Aruba 802.11a access points.
Duke University ran a pilot with VideoFurnace over wireless in their Tower Dorm for a while. You might want to contact them about their result and density of access points. From my discussions with them they had used quite a few access points to do the coverage. The point of contact at Duke is Kevin Miller.

We are testing Video Furnace. I found out today that multicast will not work over LWAPP - controller based APs.

Subject: [WIRELESS-LAN] Streaming multicast over wireless
I am working on testing streaming multicast video over wireless and
wanted to find what others have found in their testing/deployment.
I know Dartmouth is doing this on their campus. Using 802.11a radios
for this purpose.
<http://new.arubanetworks.com/solutions/case-studies/dartmouth.php>
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.
