I believe Boden uses LXC to mean 'Linux Containers' the theory, not lxc the tool/implementation.
In speaking to him he's very well aware about libcontainer.
Yes correct... As I mentioned below the tests are intended to show the benefits of an LXC based technology in the Cloud space. Docker was chosen b/c that's my preferred "LXC provider", but could have just as easily been libvirt-lxc, OpenVZ, etc.
