Not to my knowledge. If you go through the nio-dev archives you will 
find several developers and projects that have grabbed some of the code 
(mostly file system) and got it working with jdk6. They have of course 
needed to change the package name. I'm not aware of anyone attempting 
the multicast implementation, which might be hard because that is adding 
to an existing class. If you are trying the multicast support in jdk7 
then please send feedback if you run into any bugs or issues.

I didn't understand the comment about being "able to set IPv4 vs IPv6" - 
do you mean the ability for a DatagramChannel to be a channel to an 
IPv4-only or IPv6-only socket? That is important for multicasting but 
otherwise IPv6 support should be transparent.
