I've got a basic and a ridiculous question First, how can I monitor total data "consumption" at home? I'm curious how much data I use through my cable modem service, including two computers, two iphones, two Tivos and an Xbox. Maybe my ISP (Time Warner / RoadRunner) tracks and can report that to me? What prompts this is Verizon's 4G rollout. Rochester is part of the initial launch. And based on early reports (http://gigaom.com/2010/12/01/verizon-4g-review/) this service is faster than I get from my cable modem service, particular upload speeds which are over 5x faster than I get. And that makes me wonder if it's possible to setup this kind of service for whole house use by way of my Airport Extreme Base Station, as I do with conventional cable modem? And even if I can do that, I'm back to the first question, because the 4G has a 10GB cap for $80/mo, with 1GB overages at $10 each. I suspect the answers to my questions are "a lot" and "no" But with wireless services coming out that are, in practice, better than wired services, it makes me wonder if I can do better than what I've got now.
