All things related to multicast

[Alan Crosswell <>]

Aha.  Yes, you discovered this feature of multicast:-)  Depending on your 
viewing application, it can be set up to explicitly send back tracking 
information.  One example of this is many RTP clients send RTCP reports back 
which primarily indicate how well the stream is being received for performance 
management purposes.  There's also the whole area of rights management, 
encryption, etc. of pay-per-view and the like which I would like to learn more 
about from someone and can certainly be envisioned as a tracking mechanism.  Anyone?
