I think you misread his post, he doesn't *want* to do more tweaking to "get IPv6 
working right," he wants IPv6 to go away. You seem to be telling him a really 
good way to do something he is desperately trying to avoid.

If you could change polarity on your expertise in helping people install and 
configure IPv6, you could probably tell him what surgery and chemotherapy will 
eradicate it from his system completely.
