I think this is a bit to unclear in regards to the limitation of scope. My 
worry are internet wide measurements. Reading what exists in the currently 
available draft in the Section 10, there are no limitation here described to 
only use this algorithm only across controlled networks. Especially as bullet 
5 in Section 10 relies on the load algorithm what is currently written is fine 
across the whole internet as long as sender and receiver are okay with the 
measurement which is not what I at least thought we agreed.

Can you please be explicit that the load algorithm is limited to use across 
networks path that are controlled or managed and not intended for Internet 
wide usage.

 - MUST only be used as part of measurements within managed networks, and not 
across general Internet.

[RG] That's tough, as regulators are interested in this test and regulators 
aren't part of a domain. So they might resort to TCP speed tests, being less 
accurate and precise and not standardised (note that penalties are discussed 
to be linked to results). I'd be interested in finding agreement to have 
metric and method standardized for at least nations under authority of a 
single regulator. No idea how exactly. Would a bound on RTT/in some countries 
multiple instances and some additional parametrization information prior to 
start, e.g., a contracted access bandwidth, help?

[RG] I'm off for the weekend (I'm out for a lasting solution, not necessarily 
a speedy one) - regards,
