My opinion is that this is a duplication of effort and we'd be better 
off if everyone contributed to enhancing virtio, which already has 
widely deployed guest drivers and non-Linux guest support.

It may have merit if it is proven that it is technically superior to 
virtio (and I don't mean some benchmark in some point in time; I mean 
design wise).  So far I haven't seen any indications that it is.
