I did not comment before on the issue before I was also trying to decide
if evil of new swamp space is worth necessary to multi-home right away.
However I do have to agree with Lea others now and think that policy
for ipv6 micro-allocations for multihomed customers should exist.

Additionally I'd like to note that by not having this policy we may well
be delaying deployment of IPv6 in US and Canada and so North America may
well be getting further and further behind (and we're alredy behind both
Europe and Asia), I really dont think this is good and it may well get
to the point that it begins to effect economy either directly or
indirectly (as new research and new inventions on internet would shift
to where internet technologies are more advanced).
