Not at all true. Neutron, the open source implementation, uses a variety of
open components, OVS being one of them. If you know of any open component
that supports NSH readily available today, I'd be happy to hear about it.

We have actually been trying to better define what stadium means as it may
lead to misconceptions. But in general no it doesn't.

Not sure I understand this last point, if you can rephrase I'd be happy to
address any other concern you may have.
