Right now everything's a best efforts, throw everything through at the same time in the same way approach, but aren't there possibilities where prioritizing some traffic over others can be a great thing?

For example, creating a separate dedicated channel for your VoIP traffic so that calls aren't degraded whenever someone else in the house starts using P2P.

Is there any potential for a future where allowing some traffic to be prioritized over others to be a net positive for consumers, app developers, and network operators?
