Can I have the reverse? IP over USB at USB 3.x speeds?

yes on linux(usbnet) at least for a long while, not sure about usb3.x or windows support though.

https://en.wikipedia.org/wiki/Ethernet_over_USB

A quick google showed there are Gigabit NIC over USB3.0 on the market already(for a while): http://www.amazon.com/Network-Adapter-Anker-Ethernet-Support...

I don't want a USB NIC, though, I want just USB to USB with as little shit in between them as possible to be as cheap as possible. Maybe even allow straight DMA to DMA across the machines due to it being USB 3.x.

That's not IP

IP over Firewire and IP over Thunderbolt both explicitly use native DMA to accelerate it. USB only gained DMA in 3.0, and most devices that would greatly benefit from it, don't.

Thunderbolt is much closer to the PCIe bridge/RDMA style interface you seek. Not as ubiquitous or cheap as USB, though.

Yeah, that's 100% of the problem.

Intel refuses to deploy Thunderbolt everywhere, even though I have two Z87/Z97 motherboards with Intel GPU-powered DisplayPort ports and Intel could have trivially baked this into their chipset.

The only computer I have Thunderbolt on? My MBPr. The only computer I don't need a shitton of cheap bandwidth on? My MBPr.

With all the new ultrabook laptops lacking ethernet, this would be awesome!
