IPv4 vs IPv6

I know how IPv6 is not supported by everyone/everything blah blah blah, but how easy/difficult is it to link an IPv4-based server to an IPv6-based server, on the same network? I tried compiling Unreal3.2 (one of the older betas...16 or 17) with IPv6 support, but it wouldn't start because I was using IPv4 addresses in the conf. This is understandable for obvious reasons, but is it possible to have a IPv4 compiled server on the same net as an IPv6 compiled server, if so, how?!?

I haven't set it up before, but I know it's not impossible; it's just like having certain servers on your net support SSL. Once you have an ipv6 IP, simply put it into your listen {} block, except put brackets ([]'s) around it. That will tell Unreal to think of it as an ipv6. From there anyone with ipv6 enabled can connect to it. It's worth noting that Unreal handles hostmasking a little differently for ipv6, and I've seen certain instances where it can cause issues, but it shouldn't be a huge problem. Just make sure you have an ipv4 address as well so you can set it as the bind-ip in your link {} block for your leaf so it can connect to the ipv4 hub. I *think* that if you follow the instructions above, it should work okay.
