almost,

LXC starts as a general purpose Linux container with everything built in, and adds more isolation as development continues

ZeroVM starts with no general purpose Linux, and will add support as development continues

ie, LXC will work with what you have now, ZeroVM will eventually work with what you have now, but shims will have to be developed for everything, either in your code, or in ZeroVm's

IMO the future endpoint will have similar functionalty in both projects, but LXC will see more testing and use /now/
