Dunno what kind of application. But it think you should do it like github & 37signals. Make sure your software is usable for free and add some features for which real customers would pay. Dont work against piracy. Its lots of effort for nothing, because there will always ppl who find a way to crack your software - and, IMHO, thats absolutely okay. If your app is good enough, it will be pirated, but that means LOTS of ppl get to know about it and, at least, few of them will pay for.
