No, you can feed chameleon an OGC Web Map Context Document.

Yes, it acts as a client to a statelss catalog.  You can show the results of
the catalog search through the default widget, or tweak the code.

Chameleon itself is open source.  The services it connects to are public.
You'll have to contact the various providers of the services to see if the
components used to build them are opensource.

Chameleon connects to various services which are part of the CGDI and other
spatial data infrastructures, such as WMS, Gazetteer, Catalog, Postal Code,
and Web Map Context Documents.
