Hi,

thanks for changing the Subject: accordingly.

Indeed, but we shouldn't mix 6rd (which is a huge waster of "assignment
densitiy" if used with full 32 bits) and large-scale access networks 
with multiple levels of aggregation - and for these, there is some
meat to Daniel's argument about "the current HD ratio is too strict".

So I'll welcome a discussion on HD ratio in general or different a HD ratio
value, backed with numbers to make the problem clear to the AP community
(without numbers that explain the problem without people having to wrap
their heads on logarithms, it will be hard to convince the community).
