No, keysyms.  This is what the vnc protocol uses, so there is no way
around that, unfortunaly.  It takes the X11 keycodes and translates
these to us keymap keysyms using a buildin table, then sends them.  So
for the server side (from vnc protocol view, i.e. qemu-dm or vnc-fb) it
looks like a vnc client with us keyboard.

> Passing scan codes in addition to key symbols makes sense.

Does the vnc protocol allow that?  I don't think so :-(

http://www.suse.de/~kraxel/xen/, the vnc client in the "xenwatch" package.

cheers,
