If I source a 1Mb/s stream my upstream can be assured that it will use no 
greater than 1Mb/s on each of their multicast transit links... 

that may require a different billing structure than unicast but it's easy 
to measure (netflow) or bill for...

their internal network make look strange though.. if they have a full mesh 
(mess maybe) mpls network provisioned on top of their access circuits they 
may carry the same traffic more than once of the same link... such are the 
joys of tunnels.

  In Dr. Johnson's famous dictionary patriotism is defined as the last
  resort of the scoundrel.  With all due respect to an enlightened but
  inferior lexicographer I beg to submit that it is the first.
