i design catalogues for a client in the medical industry. one idea we have is to give out ipads to the top clients, with a preloaded catalogue. My first question is can i create a button that just launches a catalogue? does it have to be a pdf? Then my next question is there a way to remotely send over an updated catalogue? The client would want to be careful who received a catalogue. So we could not post on the store. thanks in advance for any assistance/advice.
