given that the app is only useful if it can make a regular remote connection to a calibre instance, have it "phone home" at the same time with some unique bits that will let you name & shame whoever distributed the cracked version ? Or do server-side serial number validation & blacklisting.
OR ( my unethical favourite) , anon. "upload" your own "cracked" & booby trapped version, with a suitably destructive payload, to the most notorious sites.... sit back & grin evilly
