Hmmm, my original comment looks like it came out my ass.

The driver is that massive fragmentation will cause significant expansion 
of the default-free routing table.  For operators who run on slightly 
older and less capable routers which are reaching their end-of-life in 
terms of fib explosion, this is going to provide them with a good driver 
to upgrade their core boxes.

I'd propose that there would be two consequences to this: 1) any new 
system they are going to deploy is almost certainly going to support ipv6 
out-of-the-box and 2) it's going to cause network engineers and - with any 
luck - bean-counters to realise that continuing problems with ipv4 have 
just taken a very large chunk out of their annual capex.  Which gets back 
to my original point that ipv6 is not going to see any level of success 
until it becomes a financially more attractive option than ipv4.

Let's rephrase the original comment as not so much driving ipv6 uptake but 
removing further obstacles to its uptake.
