What does spice need which isn't present in qemu today?

You can start qemu with both sdl and vnc enabled.  Graphic output is 
sent to both.  Keyboard and mouse input is accepted from both.  Sound 
via vnc works too.

What doesn't work: usb + chardevs (i.e. serial console), so we need some 
interface here.  For graphics spice probably needs a different interface 
than the existing for a stupid framebuffer with copyrect op.  I don't 
see a need for new keyboard/mouse/sound interfaces though.

cheers,
