I wish people wouldn't base their bloody netflow accounting systems
on perfectly symmetric traffic flows. Argh.

Its 2008 I still see the country academic backbone implement
symmetric netflow based accounting, and I get pissed off every time
a department gets charged thousands of dollars from a very much
local or internet-2 connected ISP, because of asymmetric flows.
