Hi there-
You asked who is using the nova-docker driver use cases. I am using it to evaluate how docker support can be made available in cloud IaaS.
My interest is in seeing if docker containers could provide an equally or more effective option to VM based virtual network functions in future network architectures.

Good points, Dan and John.

At this point it may be useful to see who is actually using
nova-docker. Can folks who are using any version of nova-docker,
please speak up with a short description of their use case?

Thanks,
dims
