Actually it’s not a design problem in IPv6. A simple tweak to the software to send to ff05::<group> instead of 
ff02::<group> or better yet, allow the user to edit the scope in System Preferences is all that is really needed.

However, in IPv4, mDNS/Bonjour (and mDNS is uPNP’s fault, not Apple’s to the best of my knowledge) use broadcast 
packets and that’s a design flaw. However, hard to argue with the choice since multicast, especially cross-router 
multicast is pretty much busted in any sort of home gateway in IPv4 anyway.

OK… Clearly you are determined to let cynicism and avoidance drive your ideas here. I can’t help that.

Hopefully enough others will try to make the internet more useful as we move forward and hand out larger end-site 
prefixes.
