I have met with the lmctfy team, they are indeed awesome and doing very cool work, in particular around providing a higher-level and more ops-friendly interface to cgroups for resource limitations, one that emphasizes application profiles and SLAs over tweaking dozens of individual knobs.
I really want to make this available as a docker backend, and they seemed to like the idea - something was said about Go bindings possibly coming soon :)
Not really. AFAIK, they are right now preparing the next release and there will be a lot of activities on lmctfy in 2014.
