I tried something like that a while back and while I could create the 
rules just fine, it proved to be very impractical with the amount of 
traffic I was dealing with. (around 20Mbits/sec)

I ended up using netgraph and ng_netflow(4) to export the data to 
another machine that processed all the data.
