You said "Are you convinced we need to move from the IP NGN Era to the EPN Era Yet?"

Absolutely, the rationale makes total sense to me.

Besides, from a Service Provider business model development point of view, I see huge opportunities for innovation at the other end of the stack, within the top layer (not shown in Figure 1), that being the Experience layer above Applications.

Creating and delivering an engaging or remarkable customer Experience may seem like an esoteric notion that is difficult to apply in practice. It isn't, when you know how to conceptualize.

Designing a distinct customer Experience layer -- that's focused on the needs and interests of application users -- can be applied to create an adaptive usability model.

I see this advancement as a much needed evolutionary step that complements the EPN innovation that you describe at the bottom of the stack.
