So, set your Rate-Limiting of SIP traffic to 1 packet per second for the network that YOU control and then offer your VoIP subscribers a different QOS profile at a higher cost. Bingo, problem solved. The economy will work itself out.
In fact this just happened to me here in Bangkok; I was doing some tests of streaming audio during which I was moved administratively from one ADSL domain to another. Streaming audio became unuseable with many packet discards apparently due to jitter running up to a second. (The utility at <http://testyourvoip.com> proved invaluable: it uses Java to install a simulated VoIP client and runs a broad suite of tests.) Behind-the-scenes discussions have revealed the provider's experience that a short time after it brought the service online, its bandwidth was overwhelmed by a small minority of users downloading videos etc. The solution was silently to throttle the throughput. (Same operator nightmare experienced at many institutions of "higher" education where the "students" use the ethernet jack in their dormrooms, intended for research purposes, to download sex videos.)
