Hi Anthony,

Thanks for your comment.

The problem with the solution you suggest is that all VNC traffic will 
be first sent to the unix domain socket, and then copied to the TCP 
socket. This double work may be acceptable if we're talking about one 
instance of qemu, but as I said, I run many concurrent sessions which 
create too much load. In the solution I suggest, this extra copying is 
not needed.

Shahar
