 From a quick look at the source, ExternalEditor overrides just the 
manage_main method of objectManager to provide this link, with the 
following line of ExternalEditor/manage_main.dtml (and one also has to 
take a look at findResults.dtml in the same folder).

   <dtml-var expr="externalEditLink_(this())">

Where actually this method gets called (from ExternalEdit.py):


def EditLink(self, object):
     """Insert the external editor link to an object if appropriate"""
     base = Acquisition.aq_base(object)
     user = getSecurityManager().getUser()
     editable = (hasattr(base, 'manage_FTPget')
                 or hasattr(base, 'EditableBody')
                 or hasattr(base, 'document_src')
                 or hasattr(base, 'read'))
     if editable and user.has_permission(ExternalEditorPermission, object):
         return ('<a href="%s/externalEdit_/%s" '
                 'title="Edit using external editor">'
                 '<img src="%s/misc_/ExternalEditor/edit_icon" '
                 'align="middle" hspace="2" border="0" alt="External 
Editor" />'
                 '</a>' % (object.aq_parent.absolute_url(),
                           urllib.quote(object.getId()),
                           object.REQUEST.BASEPATH1)
                )
     else:

So it should be no problem to insert any test you like there.

Do I get funding now? ;>>>
