Let me make a couple of observations. First, IPv6 is the standard for a few niches, such as 3rd generation wireless and the infrastructure for HDTV. If you will interface with these sectors, you will need to use it. I think it's also being used in some new air traffic control systems.
Second, if a company has labs, IPv6 is probably close enough that it's worth doing some familiarization. Third, in the specific example, where there is overlap between two 10/8 domains, the only practical way to get around massive renumbering is double NAT (i.e., Enterprise 1 to DMZ, DMZ to Enterprise 2). I'd want to look at specifics, but v6 might, in some cases, be useful for the DMZ. Fourth, there are still only partially understood routing aspects. Autoaddressing is more flexible in V6 than in V4, including changing carriers. Multihoming with multiple carriers is not a completely solved problem. Don't always think of V6 as a way to "get more addresses". It also has functionality that V4 does not. Indeed, the general pattern in V6 deployment is likely to use static addresses much less than V4, including the high-level prefix that may be aggregated at the carrier or set of carrier levels.
