That's what I meant by the 'as long as one is sure one isn't buying
trouble down the road' part. Having encountered problems with
overlapping address space many times in the past, I'm quite aware of
the pain, thanks.

RFC1918 was created for a reason, and it is used (and misused, we all
understand that) today by many network operators for a reason. It is
up to the architects and operators of networks to determine whether
or not they should make use of globally-unique addresses or RFC1918
addresses on a case-by-case basis; making use of RFC1918 addressing
is not an inherently stupid course of action, its appropriateness in
any given situation is entirely subjective.
