Exactly. And after having read this specification, I also think these issues

Agreed. I think the right thing to do at this point is to revise the
specification. One possible approach, and the one I'd prefer, is to simply
for NECP to only be used on the server side. Alternately, the distinction of
Let's remember that a major goal of these facilities is to get a user to a
server that is 'close' to the user. Having interception done only at
distant, localized server farm facilities will not achieve that goal.
Further, I'm unclear about the architectural difference between (and
apologies if things don't quite line up):
client --> Internet -> ISP -> Intercept -> subnet1 -> Server1
-> subnet2 -> Server2
-> subnet3 -> Server3
client --> Internet -> ISP -> Intercept -> Internet -> Server1
-> Internet -> Server2
-> Internet -> Server3
the location of the service could be made clearer and the perils of arbitrary
intermediate use spelled out.
Perhaps the issue is not location, but coherent administration?
I also see some technical issues in the protocol itself. For example, the
performance metric set seems inadequate, at least based on my past experience
with other load balancing systems. OTOH, the set is extensible, so this
could be corrected fairly easily.
This would seem to walk down the path of considering this spec as a BASIS
for pursuing a standard?
(The usual caveats, proscriptions, etc. apply with respect to IETF change
control. What we see now is likely not what they will get later...)
However, I don't see any of these technical issues as impediments to
publication as informational or experimental.
