A system that wasn't P2P-centric could be interesting, though making it
P2P-centric would be easier, I'm sure.  ;-)

The idea that Internet data flows would ever stop probably doesn't work
out well for the average user.

What about a system that would /guarantee/ a low amount of data on a low
priority queue, but would also provide access to whatever excess capacity
was currently available (if any)?

We've already seen service providers such as Virgin UK implementing things
which essentially try to do this, where during primetime they'll limit the
largest consumers of bandwidth for 4 hours.  The method is completely
different, but the end result looks somewhat similar.  The recent 
discussion of AU service providers also talks about providing a baseline 
service once you've exceeded your quota, which is a simplified version of

Would it be better for networks to focus on separating data classes and 
providing a product that's actually capable of quality-of-service style 

Would it be beneficial to be able to do this on an end-to-end basis (which
implies being able to QoS across ASN's)?

The real problem with the "throw more bandwidth" solution is that at some
point, you simply cannot do it, since the available capacity on your last
mile simply isn't sufficient for the numbers you're selling, even if you
are able to buy cheaper upstream bandwidth for it.

Perhaps that's just an argument to fix the last mile.
