As far as second system goes, at least for the host side it didn't seem 
overwrought to me. Part of the problem was that there were definitely 
politics with DHCPv6 and maybe some other things that we getting 
developed along side v6, but those were pretty easily overcome once the 
will was there.

I'd really like to understand what the requirements that are specific to 
v6 are that make it so much harder or bloated. Not product availability, 
but actual things that make it difficult to deploy.
