Status of IPv6? Is it mostly transparent?

I find just a small amount of documentation and postings match "ipv6". There is an option "-tun-ipv6" that is shown. Does that mean separate tunnels to clients, and separate TUN devices in the server, need to be configured to do both IPv4 and IPv6? Normally, an interface can be configured with multiple IP addresses in both families (though Linux still uses interface alias names for multiple IPv4 addresses ... it can just "add" them to the primary interface name for IPv6). So in that sense, an interface can do both. But does OpenVPN's IPv6 support deal with that? I'd rather have ONE TUN device instead of two to do both IPv4 and IPv6 concurrently. And can it do both over a single tunnel session to the client, or are two parallel sessions required?

Also, can I simply just use IPv6 addresses where IP addresses are used in options and commands, where it applies? Do IPv6 addresses need any special quoting, or are they parsed normally in their common form?
