	Yes, there are the hacker related issues that need to be

	With the advent of DSL, etc.. and the more people
that are entering the broadband markets, I think that this will change.
The number of people that are sending live media all the time I believe
will change.  Currently numerous radio stations are sending
live audio via (some sort of) streaming media to the world, either via
the real products, or via the m$ products, or both.  

	As more and more people get higher bandwidth solutions into their
homes, (dsl, cable, etc), there are people out there that would like to
start sending their video along with audio.  Creating the
ability for there to be a less resource intensive one-to-many system
on the broadcaster will (in my mind) allow more people to get into the
sourcing these types of sources, for either pay, or whatnot.  (Think
USA cable, pay-per-view.. they make their money someplace).

	I'm not saying that the on-demand media is not important, but
I see more and more live events also being there.  The on-demand media
will be important, but you can distribute your on-demand servers
across multiple providers, but your live media needs to be more
