N one of my friends suggested that u make use of the serial key system for differentiating bet licensed & unlicensed users... it sounds good... the first time a user uses ur app... jus ask for their key... also have an option for evaluate.. if the user selects evaluate set a preference to null string or if the user enters a correct key set it to smthin else... the key validation is a onetime job... so i guess this will also not bother ur performance...
