Well, I think the management is actually the most tricky thing here.
Unfortunaly this isn't covered very well in the usb/ip papers. Also
there seems to be no protocol specification linked from the website.
Being compatible at protocol level makes sense for direct connections
(if possible). For the usb-over-vnc and vnc-over-spice cases this
probably isn't going to work though.
cheers,
Gerd
