     Theres is un ugly workaround I'v tested for mikrotik(v5 RouterOS) 
users(who only have ipv4 behind the router) to get basic IPv6 http 
connectivity and that is by using the mikrotiks internal WebPROXY server.

As long as the router has an IPv6 and of course IPv4 address 
connectivity to the upstream provider, you can get IPv4 client devices 
that are behind the router to use there webbrowsers(IE/Firefox etc) 
webproxy pointed at the mikrotik. Only thing to be mindfull is to make 
sure the DNS set in the mikrotik points at a suitable public or ISP's 
DNS server that can also pass AAAA records.

Like I said its ugly(and its not right), but does work for basic 
http(s): requests.

As long as the router has dual stack connectivity to the upstream provider.
All you do is manually add in a suitable IPv6 DNS.
