hmmm... a little tricky! i found a workaround which looks like this: if
you modify the __init__.py of the MetaPublisher product, so that a
MetaEntry object appears in a Folder's available objects, obviously
ZCatalog will find MetaEntries. I have created an __init__.py which
registers MetaEntry objects properly but uses MetaPublisher's
constructors. This means, if you select a MetaEntry to add to some Folder,
you will actually add a MetaPublisher. This might not be the cleanest
solution but it works :) I attached a sample __init__.py file, which you
should copy to 'lib/python/Products/MetaPublisher'.

depends on your structure... what exactly is the problem? unfortunately, 
in the current version, the mp_entries folder has to stay. there are early
plans to remove it completely but this will take some time before it
becomes a reality.
