i am not a math genious and i am talking about for example serving

10.000 unicast streams and
10.000 multicast streams

would the multicast streams more efficient  or lets say , would you  
need more machines to server 10.000 unicast streams ?

well , cheap is relative , i bet its cheap where google hosts the  
NOCs , but its not cheap in brasil , argentinia or indonesia.
