 Beatiful idea, how in practice do you suggest this is done, how will
my router know if it should just ignore the TOS bytes or do expedited
forwarding as configured for given value of TOS byte?

VLANs? Different route paths? Any of a dozen other ways to limit special
processing to the networks that have paid for it and dump everybody else
into the best-effort pool?
So what you are saying is basically that ISPs should NOT offer any premium service at all over their internet access products, and only do so over dedicated provider-based VPNs, be it on L2 or L3 (MPLS/2547)? How about VoIP, should we build a parallell internet for that if we want to actually treat the traffic preferentially? If not, how do you propose we do NOT honor the traffic that we have NOT gotten paid for but that someone has merely tagged with a DSCP they know we will treat better?

I.e. my customer with two offices who run their own IPSec tunnel between, should in other words no longer be able to pay me for improved delivery without buying a full VPN offering from me (which they don't really need, or want)?
