Hi,

What I suggest is that we will send our patch' again as gpl2+ and clean the
entire stuff to make sure they are falling into the right copyright
category as required by QEMU.

I think it will be easier to me to just integrate it all to QEMU  however I
need to know if to use the Google code or not (it is anyway not a big issue
from time perspective)

BTW, another thing that need to be integrated in order to make this stuff
useful is the vmnet patch's, it is apple NAT for vms that allow guests to
have networking... (altho that it come with a trick, without certificate it
will require root permission, while hypverisor framework itself can run
without root)

What do you guys think?
