I notice you avoided the subject of a shared-memory video protocol: in that case, dropped data could leave parts of the screen obsolete.The same thing happens on a VGA console today, lets not make things harder in Xen than they are in real life. If you want to be sure that you see everything (human operator reading bandwidth is also fairly limited btw.) setup a system which logs stuff to a file inside the VM. It's a bit more complex it we every support 3D acceleration. We can't really throttle that without losing portion of whatevers drawn. For a normal, non-acceleration 2D shared-memory video driver, I imagine it will look a lot like RFB so it will be very easy to control how much work dom0 has to do without losing any quality.
