Having worked for a company that manufactured and designed what are
known as "IP flow classification" chips (specifically, Hifn, Inc.; oh,
and they could be reprogramed for protocols other than IP too,
including but not limited to ATM, and can do so at OC-192 speeds in
real-time), yes, it is entirely possible to do this, **and to do this
in an automated fashion**.  No human intervention is required.

Whether or not they actually take advantage of these chip features is
quite another issue; that's a policy issue.  But when/if a policy of
protocol enforcement goes into effect, it can happen instantly and
without warning to any customers.

Some countries don't give you a choice.  Many of their rules are
inspired or mandated by the telecommunications laws of their presiding
governments.

I don't know if this means anything or not, but my family got
high-speed broadband just last year.  It was the first time they'd
ever heard of a cable modem.  And not because they're techno-inept
either.  Rollout is slow.  But rollout is complete.  Eventually.

Just my two cents.
