Current IPv4-only services already cause communication failures, 
because they lack support for the latest standard version of the 
IP protocol and it is happening in networks where you wouldn't 
expect it:

There is a well known very large telco provider in germany who offers
broad ipv6 support, even on mobile. But their invoices will never reach 
the customer if it's mailserver is on an ipv6-only system, because they
are not even offloading to a dualstack gateway for compatibility and 
enduser support is unable to route any complaint to someone clueful.

You can do this correctly on your side of the wire by implementing some
form of translation (and you should), but you need cooperation on the 
other side. There is lot of systems out there, having Ipv6 support, but 
checking connection credibility via IPv4 (mostly seen in broken email 
spamfilter setups, but not limited to that) and some of them do it on
purpose. Some of them have been running ipv6 for a long time in their 
network, so they should know better. 

If you want to increase IPv6 adoption rates significantly from where 
we are now, just throwing ipv6 on the network it not enough. You need 
to address a grave acceptance problem: Server Admins don't want IPv6 
or are afraid of it without valid reason anymore (mostly based on fud).

People need to understand: Supporting other ipv6-only networks doesn't
necessarily mean that you have to go ipv6-only yourself. Dualstack will
be completely fine, but IPv6 is not optional anymore.
 
As Gert wrote: The network is usually not the main problem 

IMHO RIPE NCC should provide a good example by offering at least
dual stack based services for all their services without excuses.
IPv6 support should be considered state of the art now.
