Point of order...  Docker can (and use to by default) use LXC as its
backend.  Latest versions of Docker use libcontainer but can also use (I
believe) libvirt and several other backends.

The 100% cross-platform is an interesting claim considering that LXC on
Fedora currently has a problem on the PPC platform because Fedora never
released BusyBox for F20 on PPC (open bugzilla ticket).  I would throw
the bullshit trump card on the "100% cross platform" claim unless they
can support PPC, Sparc, ARM, and ARM-RPi.  And you can not migrate
containers cross-platform other than things like running an i686
container on an x86_64 host.

You've got it upside down.  It would support libvirt.  It's a frontend
while libvirt is a backend.  And, I may be wrong on this, I thought it
did support libvirt.

Indeed, they will work with Docker as core maintainers of the code. Canonical's Ubuntu container engineers will also be working on it.
