That's as may be... but the real question, I think, is this: What's the asymmetry of the *intermediate* networks? It wouldn't make sense for cablemodem providers to provision symmetric transport inside their MANs if they didn't have to... so if they *don't* have to, how hard can the push it with the way they're provisioned now? Or is the transport natively symmetric, as I suspect, and they're just letting it all sit there on the return side. Must gall their sisters... :-) Cheers, -- jra -- Jay R.
