This doesn't seem particularly useful; for compatibility with older
devices or software running on a network which only support IPv4, it
would be best if Rhythmbox continues to listen on IPv4 addresses even if
IPv6 is supported as well.

Because of the complexities of addressing computers which only have
link-local addresses (you need to specify the interface to use with
"fe80::XXXX:XXXX:XXXX:XXXX%eth0" notation, and determining that can be
difficult), it might be best to only use IPv6 DAAP if a routeable
address is configured? Unless you know a way to make it just work :)
