I don't know how good the usp/ip stuff is, but I'd be very reluctant to invent
yet annother remote-usb protocol. USB is very hairy, so there's good reason
to go with something that has already been tested.
IMO the ability to interact with the native kernel support is a feature in its
own right. If we end up with a libusb implementation of the usb/ip device
end, then that only seems like a good thing - you potentialy get testing
coverage from both qemu users and native vhci-hcd users.
