Network virtualization jargon

I've read recently this blog post Virtual Network Domain and Network Abstractions. In the post PlumGrid  CTO describes challenges and opportunities that currently exists in cloud network. In my opinion what makes it unique and interesting in comparison to other blogs concentrating on network virtualization is the language he uses.

Below are some of the examples:

• Distributed Virtual Switch (DVS)
• Physical Network Infrastructure (PNI)
• Virtual Broadcast Domains (aka Distributed VLANs) 
• Virtual Network Infrastructure (VNI)
• Virtual Network Domains (VND)

Do you believe that these concepts are more understandable when we speak about networking in the cloud. Typically described today as network virtualization, virtual network, cloud network, hybrid network or private network.
