HSRP vs VRRP for IPv6 on IOS-XE - rekindling an old flame

It's too early for me to say that. I know for HSRP I had to define a 
group for IPv4 and a separate group for IPv6. Since it looks like VRRP 
is out for me I haven't looked into that. And I have no idea about other 
options for other manufacturers or specific implementations (NSRP, GSLB, 
etc.).  I'm still hoping someone on this thread from Cisco or elsewhere 
will confirm my findings. I'll update the thread with what our direct AS 
folks come back with as well.
