IMHO most users wanting too use IPv6 _now_ will sign up directly with a
tunnelbroker.
One will see that signing up using a webinterface is really not that
hard.
eg: MSN/ICQ/Yahoo/<fill in [instant messenger/kazaa/peer-to-peer]
service>/,
Most users will work it out quite easily if they know what they want.
Unfortunatly there are not many applications that currently support
IPv6.
And as you and I and some others already said it's a chicken and egg
problem ;)
Using tools such as provided by freenet6 gives quite a tremendous ease
of use.
One thing to note is that many commonly-used programs that don't really
depend on IPv6 features like security etc are not ported yet either.
Even though porting those applications is quite easy, one simply needs
to
run through Itojun's excelent doc
(http://www.kame.net/newsletter/19980604/)
And those applications (webbrowsers, email clients, mailservers) will be
IPv4 and IPv6 capable. At least this will give webhosters the
incentitive
to start providing an IPv6 google/altavista/* and more.

One should not look at the 6bone, end-user deployment is not
experimental
nor a test. These should happen in RIR space.

No ofcourse not :)
Thats why we held the AMS-IX IPv6 Awareness Day to kick a little life
into those
ISP's, checking the assignment list* one will see that Luna, Cistron,
Trueserver,
Interned, TooFast, Demon and Hubris all got an allocation because of
that event.
Hubris even got it working on the same day!
RIPE/ARIN/APNIC could pro-actively "spam" their LIR's and push them into
the
right direction or by organizing IPv6 days like this. Notez bien that
the current
stats for allocations (see * also) is:
RIPE : 132
ARIN : 39
APNIC : 90
Now what really should happen is that the US wakes up :)
Where is a company like RoadRunner or many of the other very large US
ISP's?
Even _if_ there was an ability for people to use 6to4 relays
automatically
why should they use it if there isn't any content to connect too?
And with content I mean simple things which can be easily dual-stacked
like:
HTTP, SMTP, POP3/IMAP, NNTP, eg the basic services one uses.
* = http://www.ripe.net/ipv6/ipv6allocs.html
Btw:
$ host -t aaaa www.apple.com
www.apple.com CNAME www.apple.com.akadns.net
www.apple.com.akadns.net AAAA record currently not present
$ host -t aaaa www.ipv6.apple.com
www.ipv6.apple.com has no AAAA record (Authoritative answer)
You could give all those users a 6to4 by default, but then they can't
even
use the, imho, magnificent trailers part of the apple website over IPv6
;(
