It's a cool idea, and I'd certainly buy a couple to help the
crowdfunding ;)

Ideally, it would need to be self-configuring, though... I.e., something
like the IQRouter auto-measuring of the upstream bandwidth to tune the
shaper.

For reference, the GL.iNet routers are tiny and nicely packaged, and run
OpenWrt; they do have one with Gbit ports[0], priced around $70. I very
much doubt it can actually push a gigabit, though, but I haven't had a
chance to test it. However, losing the WiFi, and getting a slightly
beefier SoC in there will probably be doable without the price going
over $100, no?
