Couldn't this be implemented into the resolving DNS, in that it could 
include priority information into the DNS response sent to the host that 
does the initial connect? Or it could be done via reverse-DNS (in the case 
where the "called" party needs to know which IP to send to when there 
are several to choose from)?

Perhaps one state in the shim6 initiation could be to do reverse-lookup 
and via some record there gain knowledge about which IP should be 
prioritized? This means that routingpolicy needs to be somehow implemented 
into the DNS server, which would require new code there as well.
