That's what it really boils down to. How much money can be saved versus 
performance. If I'm doing a lot of throughput to a specific network, it 
makes sense that I might want to connect to them, especially if that 
connection either 1) saves me money or 2) gives me superior QOS/load 
balancing without a cost increase.

Anything less than 200mbit of traffic isn't even worth me considering 
these days, and as I grow, I'm sure that number will increase. Content 
providers generally won't peer unless you meet certain traffic 
requirements for the same reason.
