i don't understand your message.. not setting the Ticket here does not allow unencrypted VNC 
traffic? in 'qm vncproxy' we die if the ticket is not set, and even if we'd not,
the vnc server from qemu does not listen on a public ip, but on (or ::1)

but yeah, we can look at that after your vacation ;)
