[Haskell-cafe] Tips for deployment?

[Günther Schmidt]

Hi all,

my haskell app is getting closer to shipping and what I need to do now is  
to give product protection some thought. The product is for hospitals and  
therefore a very limited set of clients. I do not expect anyone to try to  
"hack" my application but I need a basic protection mechanism in place, if  
only to check for a valid license key.

As I've never done this before I'd be grateful for some suggestions here.
