Aren't the two statements above inherently contradictory? If the "other 
network traffic" is TCP, then how are the bandwidth resources shared 
"fairly"? While in no way advocating the TCP way of doing things, I don't 
see how this scheme could be max-min/proportionally/tcp fair if there is 
other non-MetaContent traffic on the network.
