[Zope] removing objects from database

Hi, Is there any way that objects can be removed in such a way from the ZOPDB that the removal can never be 'undone'. Ie, packing the DB after the removal would give this effect, except that I don't want to have to pack every time I remove an object, and I only want to stop retieval of certain objects that are deleted. Any suggestions appreciated terry -- Terry Kerr (terry@adroitnet.com.au) Adroit Internet Solutions Pty Ltd (www.adroitnet.com.au) (03) 9888 8522 0414 938 124
