We did 6" of exterior rockwool, triple pane windows with storms. GREATly reduces outside noise.

It is not cost-effective immediately, however adding that much insulation on the house has about a 15-year payback on heating an cooling costs so it is cost-effective in the long run. Rockwool makes the house fireproof too.

I work for Akamai; Akamai does offer a general-transport better-than-BGP service called Sure Route IP.

The idea is that we utilize the massive amounts of data about the Internet's health and the insanely scalable alogorithms for matching end-users to the HTTP server that can best serve them (called mapping) to create generalized IP tunnels that send traffic across "routes" that know more about the Internet then BGP does.

Think about it. . .BGP routes based on the least number of hops. . .there are many problems inherant in that. We route based on ping data, bandwidth, cost, reliability, etc, etc, etc.

Did I mention that we are hiring like crazy?
