I have no experience with libvncclient. I think the general idea of using VNC to create an external QEMU GUI is a good one. Previously, I had posted some patches for a shmem GUI that used a custom control channel. After hacking on that for a little bit based on some feedback, I've come full circle and am now under the view that extending VNC is a better long term approach.

So, I've reserved some pseudo-encodings and a client message type and am now working on some VNC extensions to enable better QEMU integration.

My current client code is available at:

http://hg.codemonkey.ws/vnc-gui/

The VNC extensions are still a work in progress but documentation is here:

I think this is a good idea. First one detail: for Pointertypechange, it would be better to use the value 32768 as 0 instead of 32767 or to use a 16 bit two complement value.

Another point is that you should consider adding audio support. I can help you on that (maybe malc would be interested too !). A simple format could be 4 bit ADPCM at fixed frequency. Optionally A more advanced codec such as Vorbis could be used.

Fabrice.
