You shouldn't access the OpenLayers layers directly, use the MapQuery
API. In you case you have to use a bit of OpenLayers directly, as you
add a new layer type. Though you should just be able to add a new type
and then use the MapQuery API from then on. If you still need direct
access to OpenLayers, you either do it wrong, or you use something that
is not supported by MapQuery. In the latter case, feel free to tell what
you miss.

When I call $('#map').data('mapQuery').layers(); in the LayerManager
example I just get 2 layers back as expected, no sign of the
OpenLayers.Layer.Vector.RootContainer.
