Well I'm not coming from the telco side of things, but I did my telco homework when I got into brick and mortar IT. That knowledge came in handy as the Internet age bloomed, and after I moved to engineering colo facilities. Sorry for talking down to you; I didn't realize that you were a pro. I understand you so far as you're saying "this is how you set up a computer network to handle VoIP calls best". What I'm saying is that it's not a law of nature; you can break the rule. I'm saying that a company like Sprint can break that rule if and when mobile data users become the squeaky wheel. I don't know why for sure, but I have a feeling this might happen soon. If we go back to my original heresy and look at that tasty 2.5GHz spectrum and how it could solve all of Sprint's current problems if only they could get it intact, stuff like this wouldn't matter. But because it does seem to matter, we might as well think about the unthinkable just in case. Sure most people don't know (or care) how DSL works. Most people don't know or care that cellphones are radios. America has become a society of mindless consumers. But that's for another topic.
