Any way you do limiting depending on any level over L3, you're going to 
fail in the long run (people will start to move ports around or go 
encrypted).

My suggestion is to do marking on comitted bitrate, ie make sure that 
people get a certain amount of bandwidth per IP, mark excess traffic, and 
drop this excess traffic when you get congestion.

Either that or give up and give your customer the bandwidth they want and 
need, which is the preferred and least complicated solution (apart from 
Layer 8 problems).

If you need to drop traffic in the core or distribution, your access speed 
business model is flawed.
