neat :) didn't know about this.

Yep.

Though I would prioritize A+AAAA web setups below other tasks, since web 
content has the greatest possibility of meeting a misconfigured user, 
who cannot figure out what went wrong.

Agreed...  unless native IPv6 is estimated to be years away.

Internal pushing at RH has yielded very little result...

Best googled estimates are "probably by the end of 2009"

That's the good news.  ibiblio has been experimenting with IPv6 for 
years:  http://theclassicalstation.org/press/2004_ipv6.shtml


Also, another DNS issue:  getting AAAA glue records served by the .org 
registrar.

Technically this is true... but it is also true that most users are 
still doing IPv4 ;)

I tend to look at DNS as a "sooner rather than later" hurdle, because 
that is the first link necessary to construct an all-IPv6 path to the 
destination servers.
