Well, the point is that 6rd does *not* require another prefix per ISP, if
done within their LIR allocation.  As opposed to announce umpteen IPv4
prefixes that this LIR holds as more-specifics under 2002::/16.

A second prefix for 6rd is only required under the proposal that a LIR
could get a second (larger) temporary prefix to deploy IPv6 via 6rd, and
later return that when all the network has migrated to "native" internal
IPv6.  I'm not convinced that this is a workable approach, as the criteria
for "this has to be returned, if ...!" are usually quite hard to judge
from the outside, and people tend to forget about good intentions...
