Certainly difficult when you bring being a Wifi AP into the mix.  This is
where a two-box solution might work better, running something like the wndr
as an internal router/AP, and using a separate box for the high-speed AQM
for the edge routing?  A dual-port GigE platform seems like it would be
easier to find (or build via mini-itx).

I'm nearly certain that something like a dual- or quad-codre i.MX6 at >1GHz
could do the work, but those just aren't available in a "home router"
package, which is the killer.  The fact that the home routers are commodity
products, and built to cost with a very narrow feature set makes it
exceedingly difficult to locate platforms that are viable for
experimentation.

Basically, we need a high-performance-networking version of a Raspberry Pi.
