If we can easily detect > duplicate clients avaliable in both networks, then we could support both. Then perhaps: 1. Libdmapsharing serves on both IPv4 and IPv6 as available. 2. As libdmapsharing is observing DMAP services on the client side, it could check to see if a hostname, service name, port tuple already exists. If it does, it could skip adding the service. Right now, I don't think either will require any change to Rhythmbox proper. There might be a problem with other clients that do not check for duplicate services. There has been talk about IPv4 + IPv6 being a problem for mDNS/SD in general because of duplicate services. I know that some distributions were shipping with "use-ipv6=no" set in avahi-daemon.conf for this reason. -- Mike :wq _______________________________________________ rhythmbox-devel mailing list rhythmbox-devel@gnome.org http://mail.gnome.org/mailman/listinfo/rhythmbox-devel
