Are you sure 4.87 does have Media API, iirc it should already have it
but it is disabled by default but you can enable it via audio.conf
Enabled=Media. Btw, MeeGo should be using that since the old unix IPC
has some problems and should be deprecated pretty sonn.

The idea was that whatever system that does have DBUS_TYPE_UNIX_FD
should use Media API to exchange fds, it seems you are trying to
workaround this which IMO is not a good idea.
