It seems this would give similar performance to Xen 1.2, while retaining most of the benefits of the NGIO model (i.e. not having to port drivers). The only downside would be the lack of driver isolation, but most people would be willing to live with that is my guess (plus as long as there is no IO-MMU a bad driver is still able to take down the complete system anyhow). I imagine this could be done in a way that would also work under other host-OSes, like *BSD or Windows. Any comments?
