I tried to google for G3-PLC, got to:
    www.g3-plc.com which redirected me to:  http://107.170.210.217/
which is clearly a very much non-IPv6 compatible address for an entity that
is supposed to be deploying millions of IPv6 devices... this really does not
inspire confidence in me...

I knew what PLC was, but not how G3-PLC differs... can you clarify that it is
in fact a mesh-under technology?  What is the mesh protocol, and where is it
defined?

Can you clarify if G3-PLS is in fact using both mesh-under and route-over
technologies at the same time?

The proposed changes do not deprecate anything; they really just make
mesh-under and route-over unable to operate in the same PANID.

Having said that, I am not in favour with doing even that, but I want to make
sure that people clearly understand how minimal the impact.

As Ralph said, *PLEASE* respond via a Liason statement as that we can get
this into the right records.
