[Spice-devel] [Qemu-devel] RFC: usb redirection over the network, interesting outside of spice?

Doesn't look very useful on a quick glance.

First: Yes, we wanna embed this into other protocol(s).

Second, seems usbip is implemented using special drivers in kernel space 
for both sides.  We will not need special drivers on the qemu side (we 
just hook up the devices to the emulated hci).  On the client side using 
libusb looks alot more sensible than requiring kernel modules.

cheers,
