 From experience, (see: http://www.nanog.org/mtg-0405/pdf/lewis.pdf) I 
have done this.  I don't think I spent much time on that in the 
slides, but we did start with things like "ww6." and "ftp6."  It let 
us put up servers in a production environment and see them 
functionally work.

But the value in doing this is limited.

First, it can't/doesn't draw enough load to give an accurate feeling 
of whether "IPv6 works" because the only ones that know about it are 
those you tell.  (Not that IPv6 volume is all that great.)

Second, it isn't stable (long run) because you have to eventually use 
the same names for all network (IP) versions.  You'll have to ween 
the early adopters off the special names at some point.

I would say that this is something folks should just do to make sure 
the servers come up and answer.  But it not much of a "coming of age" 
step.
