No doubt - it also points to multicast itself needing a bit more sanity 
and flexibility for implimentation.   When you have to tune -every- 
l3 device along the path for each stream, well....

As Owen pointed out, perhaps carriers will eventually be motivated to make 
this happen in order to reduce their own bandwidth costs.  Eventually.

In the meantime, speaking with my content hat on, we stick with unicast.
