I can confirm that the ICMPv6 redirect when I communicate between a FBSD 
box, and ::b6 (FBSD) is not generated by the router.

It only happens from my XP box. I'm going to try Vista from a colleagues 
workstation to see the effect there.

I personally don't like it. Just adds overhead to the router. Hopefully 
I track it down to a config issue at my end.

Hopefully someone else has a setup where this can be tested and 
documented that requires minimal effort to do so, just so I can compare 

Also, any other feedback as to how to troubleshoot this further from 
someone who knows the innards of Windows better than I do (I'm purely a 
FreeBSD person) would be great.
