Sounds like cool stuff.... This should fit nicely into what is now fashionably called SDN... Now I got to figure out a way to glue this to my home-grown vmrun.sh stuff. And the ultimate step could be to see if it matches the things that openstack trieds to do for networking. Looking at it right away. But seems that it is getting harder and harder not to want to understand/write python. --WjW
