Been waiting for this & it's finally arrived!

Probably the coolest & most underrated feature yet!

LXC on the new release supports User Namespaces: (was not quite 'there' 
until now)

`lxc-checkconfig`
--- Namespaces ---
Namespaces: enabled
Utsname namespace: enabled
Ipc namespace: enabled
Pid namespace: enabled
User namespace: enabled
Network namespace: enabled
Multiple /dev/pts instances: enabled

This means that you can spin up a small LXC container, load a desktop 
spin of your choice, & then `ssh -X` to an app to have it run in an 
isolated sandbox with hardly much additional overhead.

Very, *VERY* nice!
