Currently the cdda plugin uses the old dvd-tracks trick to add it's track.
The cddax plugin should not do that. Rather if you play the entire cd (with
cddax://) the plugin should run playlist_ItemToNode on it's playlist item,
and then playlist_NodeAddItem() for each track on the cd. Now information
about the entire cd (like album name, data ...) can be added to the node,
and info about each track can be added to that tracks item. (I think only
name and duration are supported now, but that should be improved in the
future).

For each track the duration is fetched with the ACCESS_GET_LENGTH command to
pf_control.

No there isn't. But feel free to ask here any time.
