Since flow studies are confidential information, I will not quote from them.
However, I will say that I would think it intuitively obvious to almost anyone
on this list that Web Hosters don't OFFER very many packets that aren't a
response to a REQUEST.  Now, if we were discussing a large content provider
that hosted alot of push-oriented sites, that might be a different story.

Ah, but with the advent of providers that focus primarily on access and other
providers that focus primarily on hosting, the similar number of octets concept
is disappearing.  Not because one side is changing the balance, but because
both sides are changing.  More and more of the access providers are becoming
larger and larger sinks at the same time that the hosting providers are
becoming larger and larger sources.  The shifting of the traffic flows is
changing at roughly the same rate on BOTH sides, not because of one sides
business model.

Also, long distance phone calling didn't introduce the concept, it was around
prior to telephones.  Look at how shipping was handled on catalog orders in
days before telephones.  Generally, the purchaser pays shipping in almost all
commerce.  This has been true for a very long time.

I _REALLY_ don't see that much of a need for changing the way things are.
If the access providers cannot deliver the packets their customers request
from the point they say they want to receive said traffic to their customers
for the price they are charging said customers, then they need to reevaluate
their pricing model.  Similarly, it is the responsibility (IMHO) of the
content provider to deliver the packets to the requested handoff point.
