You should be able to do this with an ACL on your Vlan. It would be
relatively easy to contain it within the residence halls. Or you
could turn off multicast on the vlan. However the remainder of campus
might be done by restricting initiation multicast streams to certain
IP addresses on an ACL.

Writing another email, made me think of this question:
IF you multicast enable your Wireless infrastructure, can you prevent
students from initiating a multicast stream?
Essentially, do I have to worry about a student broadcasting from his
wireless laptop with a free copy of VLC? (We used VLC to test our
Multicast infrastructure)

Subject: Re: [WIRELESS-LAN] Streaming multicast over wireless]
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.
