Who is going to take the lead getting this moving? What would be really
helpful from my point of view is some form of blog/doc showing how to
get LAVA to do something useful by testing on OE image in some form of
vm. This way we can get a feel for what LAVA can do, without having to
setup a master image on some real hardware.
