	They seem to be setting their customers up for a head-on collision with the European Union's net neutrality rules, according to which "special services/fast lanes" are permissible under the condition thay they are realized with completely dedicated addition bandwidth. Just looking at their patent diagram there is one common input path to the classifier. So either that fast lane is not going to be a paid for fast lane, or the ISPs rolling this out will be in hot water with the respective national regulators (at least in the EU). The one chance would be to give the end-user control over the classification engine, or if the strict priority path is only used for ISP originated VoIP traffic (I seem to recall there are weasel words in the EU rules that would allow that and ISPs are doing something like that already, and I agree that it is nice to be able to field an emergency call independent of access link load).

Best Regards
