Oh, for sure. That's easy enough; it's what GL.inet does: They sell router-shaped computers that run a skinned openwrt -- out of the box. (There's been some questions about GPL compliance over the years, but that's a separate issue.)

And superficially, it sounds like a straight-forward thing for me or anyone else to do here in the states, but things get murky quickly: What differentiates a foreign-made router from a US-made router?

Can I get some flunky push the button in his studio apartment in Idaho to flash open (but globally-sourced!) firmware onto some boxes from Alibaba (in exchange for startup promises) and call that good enough?

Do I have to spin up the boards here in the States? And the ICs, too? How about the passive jelly-bean parts like the capacitors and resistors and the antennas?

What of the rest of the device? Like, things such as the housing, the packaging, the power supply, and the included ethernet cable: Do I need to source those from domestic US production or is it OK if they're foreign-made components?

Do I have to produce the software in the States? (If so, Linux is right out.)

Where is the line drawn? How is the line shaped?
