Fundamentally the world of packets changed the model of communications forever from one of accessing a stream to establishing a session.  Streams are continual and choose to use them to transport, while sessions are virtual and you create them and send them off from your easiest access point to the ocean of packets passing by. 

Why the crude metaphor?   We are again at that point where the Internet is being challenged at its very core.

Fundamentally the pricing model of streams is being applied to sessions. 

The reason this is important is because the application war is heating up and questions about how numbers are being connected, applications are being allowed on networks and carriers are behaving are driving congressional letters.

If you do not want the sessions to be priced based on usage send me a note.
