We did look at that (I presume you mean 'coloring' etc.) - at the moment we do

'natively' supported by AltQ (besides the fact it was a little out of my

I now happily have MRTG running off a few ipfw rules that count traffic... :)
- Seems to work pretty well, especially looking at the graphs... For
