For better TCP scaling, I'd be curious to see how your data set would 
look like if the NAT used endpoint-dependent mapping with aggressive 
port overloading for HTTP connections. Since HTTP clients often connect 
to several different hosts in parallel, multiple connections could share 
the same source port. And HTTP doesn't need EIM for NAT traversal.
