Are you explicitly passing in an ipv6 address when sharing the activity?

Other work that needs doing is switching Avahi over to ipv6 by replacing
avahi.PROTO_UNSPEC with avahi.PROTO_INET6, and adding "ip6_address" dict
items to the properties of all the PS objects in place of where
"ip4_address" is now.
