This is badly needed in my humble opinion; regarding the wireless LAN case described, it's true that this behaviour would be technically suboptimal, but interestingly the real reason for implementing it would be maintained - economics. After all, the network operator (the owner of the wireless LAN) isn't consuming any more upstream as a result.

Yes. An important factor in future design will be "network friendliness/responsibility".
.. or we could start talking about how Australian ISPs are madly throttling
P2P traffic. Not just because of its impact on international trunks,
but their POP/wholesale DSL infrastructure method just makes P2P even
between clients on the same ISP mostly horrible.
Similar to the pre-LLU, BT IPStream ops in the UK. Charging flat rates to customers and paying per-bit to wholesalers is an obvious economic problem; possibly even more expensive to localise the p2p traffic, if the price of wholesale access bits is greater than peering/transit ones!
