Achraf,

That's an interesting application - a video-on-demand service that takes 
advantage of multicast, but making multiple requests that arrive within a 
short period of time use the same multicast stream.

It's good that you were able to implement this by defining new subclasses, 
rather than by modifying the existing code.

I'm not sure yet if I'll add this to the released LIVE.COM source code 
(because it's for a rather specialized application), but if others are 
looking to do something similar, they should find your work useful.

Thanks for letting us know.
