Also critically, it's about the latency introduced by the coder/ 
decoder and by any buffering necessary to account for variable latency  
in the network.

Streaming MP3 might sound really good, but it does so at the expense  
of lots of buffering that compensates for the variable latency of the  
network and associated TCP transport. Trying to use it for a phone  
call would not work so well, unless you're used to making phone calls  
to someplace well outside lunar orbit.
