Looking good...

yes. Try to use kipi plugins with a different host like digiKam or kimdaba...

Take a look in DigikamKipiInterface implementation (file joined) :

DigikamKipiInterface::DigikamKipiInterface( QObject *parent, const char *name)
                     : KIPI::Interface( parent, name )
{
    albumManager_ = AlbumManager::instance();
    albumDB_      = albumManager_->albumDB();

    connect( albumManager_, SIGNAL( signalAlbumItemsSelected( bool ) ),
             SLOT( slotSelectionChanged( bool ) ) );

    connect( albumManager_, SIGNAL( signalAlbumCurrentChanged(Album*) ),
             SLOT( slotCurrentAlbumChanged(Album*) ) );
}

using slotSelectionChanged and slotCurrentAlbumChanged must help you fro that. 
Are you see the beta documentation about libkipi at this url :
