That would have been nice.  But I gather some of the higher-level 
protocols are different, using pecific features of IPv6, and protocol 
translation may not be trivial.  That said, it's probably somewhat 
feasible to so a somewhat decent job.  The basic problem is that the 
IPv6 inventors had not planned interoperability between IPv4 and 
IPv6.  They had some idea that everyone would gradually acquire 
dual-stack systems that could operate in both modes.  But in real-life 
terms, that hasn't happened.  Oh, countries who were originally 
allocated a critical shortage of class A networks have already gone and 
done this because they had to.  But North America is a holdout.
And the annoying thing is that most current OS's, such as Windows, OS/X 
Macs, Linuxes already are IPv6-capable.  It's the ISPs that are the 
bottleneck.

I actually don't know which routers do IPv6 and which don't.  I suspect 
in any case that it's just a firmware change.  If the manufacturer still 
suupports that router model, anyway.  Otherwise firmware might be  hard 
to come by.
