Neat. URL?
Does the linux kernel keep track of {caps,num}lock state (+leds) with
the keyboard in mediumraw mode? Or does it expect the userspace app set
the led state then?
No UI client (neither vnc nor spice) knows the guest keymap btw.

Anyone tried to bug vmware to open the specs for the existing extension?
cheers,
