I've extended the picture here - the kqemu platforms I'm aware of are  
Linux, Windows, Solaris, BSDs, BeOS.
Mac OS X was not among them. And kqemu for Solaris is already  
partially CDDL in addition to GPLv2.

You, plural! :)

As a matter of fact, with KVM the pace of development has become hard  
to follow - within days there are hundreds of mails in your inbox.
My point being that it's nice if this leads to shining new cool  
features for all of us, but not so nice if suddenly put under the same  
pressure to deliver features. For example, compare a KVM upstream  
patch not being reviewed for a week to Cocoa being broken for a number  
of weeks during the DisplayState refactoring or ppc host being broken  
for months during TCG conversion - different paces.
