RE: draft-ietf-ipv6-ula-central-02.txt

So why are we expending so much effort getting them to switch to IPv6
earlier?  When IPv6 is the mainstream method of addressing they will get
swept along.  If a network admin wants to drag their feet and do things
the hard way they have a right to do that.  The rest of us don't need to
go out of our way to accommodate them.
