Containers are zones are great if you're building your own platform that you control.
However I'm not sure building a multi-tenancy hosting environment based on containers or zones is the best idea.
Suppose the tun driver has a bug in it which can cause a kernel panic under some circumstances and that someone running OpenVPN in a container or zone hits this condition. You can now wave bye bye to all the zones running on that host.
That is one way of doing it and I've done similar migrations using a similar method in the past. A lot depends on your existing infrastructure and how your application works.

Big enough for travel but compresses down pretty flat if all you're carrying is a laptop and a few bits.
