Yes, that makes sense. Do away with what works and switch to what  
doesn't. (Granted, just in this particular case, but still.)

On a completely unrelated note: as I said before, I'm keeping my  
6bone prefix and have it published in the DNS for at least  
www.muada.com until it doesn't work anymore. This is a small protest  
against the nonsensical "we invented something new for no good  
reason, now go spend lots of money implementing it" * attitue that  
prevails within the IETF from time to time.

I am of course in no way recommending this for production stuff.

RFC1886/2874/3152/3596 debacle.
