What's everyone doing about Streaming?

Subject: What's everyone doing about Streaming?

I recently inherited an environment that allows
streaming to virtually anywhere, and it is definitely
impacting our bandwidth.  I could really use some
advice on what to block, and what not to block.  I
know that there are some legitimate streaming sources
out there (microsoft, webX, etc), but I would like the
ability to deny most of the video/audio streaming
traffic generated by end users.  Thus far, I've only
been able to come up with these 3 UDP protocols to
block:

1558 UDP StreamWorks
7000 UDP VDOLive
7070 UDP RealAudio

It seems like everyone does automatic shifting to port
80 or 8080, though, so is there anything further I can
do on my firewalls to help minimize streaming?

Thanks in advance,
Dave
