[acm] 
This change is fine with me.

[acm] 
Thanks for your suggestion.
I added " (which is 1,000,000 bits per second to avoid any confusion)"
in 5.6 and 7.4. (this may have been an earlier comment intended to apply everywhere).

[acm] 
We share that experience. Others might ask, "what's a kibibit?"

[acm] 
Thanks, I re-wrote that sentence as follows:

Fostering the development of protocol support for this metric and method of measurement is also a goal of this memo (all active testing protocols currently defined by the IPPM WG are UDP-based, meeting a key requirement of these methods).

[acm] 
It might, except we would then have two sentences in a row (with the change above) beginning:
Fostering the...
Supporting the...

I left "The supporting" as-is.
