This is what we do with Speedify: it's a VPN that uses all of your Internet connections at the same time. By the time we started dealing with issues like jitter and loss the level of effort exploded into years. That said you should check it out: http://speedify.com/

What you have described is Connectify's Speedify, it's a VPN that combines multiple internet connections together. As of the latest release it handles both jitter and loss, please check it out: http://speedify.com/blog/speed...

In fact, this does exist off the shelf already, it's called Speedify, and it's a VPN that uses all of your connections together: http://speedify.com/

Alex here, and, while that's a good observation, it's not that simple. As I described, this was the business setup. Comcast gave me two cable modems, one for my office and one for the Xfinity hotspot. The power I measure was solely for the hardware that was required to run the Xfinity hotspot. The question is, how different is the setup of consumers? They do share one modem, but in my experience most people are supplying their own wifi router (by linksys or similar) to give themselves a wifi network, in which case the fixed overhead of Comcast's wifi router is entirely there to supply the Xfinity Wifi.
