True true.  But here in Denmark, though, every ISP is legally forced to keep
copies of all traffic two years back. Which is why I cannot mess with these
fields. It's part of our new great anti-terror thingy-dingy. Something where
politicians go and say "we need this! and this!" and don't have a real clue.

But can anyone enlighten me on the runtime of flow-tag.. I described my
question in the mail before this one. Right now I'm filtering out separate
copies per-subnet, because I need to do 4 different statistics for each
subnet, because I figured that flow-tag wouldn't be the way to go.
