Haha, not a bad idea. Realistically, some sort of shaping is required
otherwise the connection becomes unusable. Too much, or blindly rate
limiting by port, is definitely a bad thing.
ISPs should rate limit, but it should be based on the CIR/PIR... give
every connection a 2Kbs^-1 CIR, 32kbs^-1 PIR, allocated from a total
bandwith pool.
Not being involved in ISP operations I'm not sure how well that would
work in practice, or if it would scale from small business grade
bandwidth pool to a large scale residential deployment. I know for
example that PF under OpenBSD/FreeBSD is limited in precision by timing
factors (quantum cycles, clock resolution etc.). Add to that the number
of lookups necessary for determining which packets to send/queue/drop,
and it is likely it just isn't technically feasible to do it that way.
