You said, "If I feel like using..(someone's) performance improving gizmo,
it's my decision." The problem with this is, in the DI example, it is not
your choice. I suppose if you're confortable with the idea of rogue
companies trying to enhance internet traffic on their own, whether you agree
with the methodology or not and giving you no choice, then that is your
perogative.

While I agree there may be unintended consequences, even to the point of
poor performance or effectively DoS'ing a site, this is not really
relevant, or the province of the IETF. If I feel like using cisco's or
DI's or Joe-The-Web-Guru's new wiz-bang load-balancer speeder-upper
performance-improving reliability-enhancer on MY WEB PAGE, then that is MY
decision.
Period.
And the IETF, IEEE, RFC-editor, NANOG, EFF, PTA, SPCA, or any other
alphabet organization has nothing to say about it. (Assuming, of course, I
am not violating standards, attacking people, etc.)

Unfortunately, it *MAY* be that DI is violating that "assuming, of course"
part above. I honestly am not sure why they would need to send 2400 pings
in 3 hours. But I am also not 100% certain that sending 2400 pings is
excessive or "wrong". Suppose the end users on that network asked for 500
GB of data from 100 DI customers?
Honest, I do not know the answer, and I doubt most people here do
either. Without knowing the circumstances on both sides of the connection,
it is a bit difficult to say "You did a BAAAAAAD thing". IMHO, of course.
