For me, this seriously comes down to ease of deployment.  I don't have 
to duplicate servers just for v6.  Infact, all I have to do is add a v6 
vip and I'm done.

Oh, and it lets me roll v6 out in a production manner, HA and all.

I do agree that the traffic level is nearly insignificant but the fact 
that my vendor supports it and I don't have to manage yet another 
system, makes my life easier.
