I don't believe they offer QoS, since they don't operate the access networks to their customers. So maybe QoS in their minds is between their servers, but who cares. The bottleneck is on the access network (DSL or Cable Modem) and that is where you need QoS for video calls IMHO.

OK. OK. So, we're all in for the Stupid Network. And, you're absolutely right on about product versus service differentiation. But, does marketing ever tie to actual product technology definition. Not necessarily, and it's up in the air whether the rich IP media industry defines (and educates the consumer on) a new set product definition metrics. Time will tell.
