Jon I know you're reading, read this : http://www.apple.com/legal/contact/includes/copyright-agent.... which will get the offending apps taken down (or you can hire a lawyer to sue Apple, which should be easy because lawyers love to sue companies with billions of dollars in the bank)
Since these folks are often "related" in that the developers that use these sorts of tactics to make a quick buck are related, if you are persistent they will get the message that your apps are a pain to copy and generally will stop, although you may find it useful to retain a law firm to go after them on your behalf.
While I would also suggest the DMCA route, I can tell you that you will experience the exact same effect (no obvious response) observed by the OP.
