Some took it on themselves to convince the authors that the concept
of network renumbering as a normal or frequent procedure is daft.
Their comments, if they result in improved address management
practices in networks, may be the best contribution this note has to
offer.

Without PI space for customers, both renumbering and traffic
engineering/redundancy for the enterprise customer become a) horribly
complex and b) subject to the whims of business relationships.
Neither of these conditions is tolerable for those customers; turning
every host on the network into a router via a Shim-6-like mechanism
isn't, either (can you imagine help-desks who can barely cope with
basic Windows issues trying to support Shim-6, heh?).
Until these issues are resolved, widespread adoption of IPv6 by large
enterprise customers for general-purpose networking will be
problematic (note that these aren't the only issues, but they are
gating issues which render the others moot) at best. Vendors,
network operators and those participating in standards bodies must
understand the seriousness of these issues for customers and work to
address them (pardon the pun, heh).

One of the main causes of the fall of the Roman Empire was that, lacking
zero, they had no way to indicate successful termination of their C
programs.
