By default, all appengine apps can be accessed over ipv6 (at least with their appspot.com names). On the outbound side, you just do a urlfetch.fetch on a URL which has a domain name that has an ipv6 address. I don't know if they use a happy eyeballs approach -- I suspect not. I suspect that they use IPv4 for the fetch if an IPv4 address is associated with the domain. If the name is ipv6 only, then the urlfetch.fetch is performed using ipv6.
