I was working a bit on this issue since we face the same problem. If you
don't mind using Python MapScript instead of the Mapserver CGI then you
could try to use this Python class that uses the OWSRequest
functionality of Mapserver/Mapscript:
http://svn.pmapper.net/repos/owspy/trunk/
It modifies the map object before the output of the GetCapabilities
response. For a group of layers always the first one in the map file is
used as the one visible to the clients for the capabilities. In
addition, only the layers that have a 'ows_title' metadata tag are
included in the response. And with an Apache rewrite rule the URL's can
be set to look a bit nicer. Some more details are in the README file.

Hi,
I would say that if it is not possible at the moment to make a logical WMS
layer that automatically swithes between several external overviews and the
original imagery through tileindex according to scale settings, then it would
be very useful to have. However, it feels so obvious demand that I would be a
bit surprised if there is not such an option. Anyway, if it is missing then I
will give +1 for feature request.
There seems to be an option called wms_layer_group in the layer metadata
section of mapfile, but I must admid that I do not understand what it stands
for.

Aihe: [mapserver-users] Re: Hiding overviews
Hello Jacob,
thanks for your try but this didn't help, sorry. IMHO the
problem is that there seems to be no way to declare multiple,
scale dependend data sources for one layer (in a WMS sense).
Since the only reason of using of overviews for me is the
(nearly) scale-independent performance. But optimization is
_really_ a private thing of the service. It is not of the
client's interest that MapServer internally organizes
overviews as multiple layers...
