multiple destination address issues

Hi,

Not sure how many of you are also in v6ops. However, you may want to 
read v6ops-v6onbydefault-02.txt as it has a discussion on issues 
surrounding multiple destination addresses. The trouble is that by 
running dual stack this automatically raises the issue of selecting 
which address to use because you can connect over IPv4 or IPv6. Most of 
the issues discussed in this part of the draft are relevant what we're 
doing here.
