Not a valid argument.  When ipv6 gets widely used then the DDOS will 
follow it.  I have to agree with the previous poster about not wanting 
to move until his DDOS mitigation gear supports V6.  Many of the 
security products i use are just now starting to go v6 capable.  I would 
not want to move to V6 even if i could until all of my security 
gear/software is properly V6 tested.
