Could This Be The Answer To Pirated Music?!

I was thinking the other day about how to secure your music so it wouldn't get pirated.
(for just a while back, a friend of mine got a piece pirated, thankfully the person finally took it down, just after some strong persuasion. ;) I'm not too concerned about one of mine being stolen, but my idea would certainly prevent it) I know there are other people asking about watermarks, but this could be the biggest hit with those who are scared about their music being stolen

So this would possibly be a good feature in Musescore:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Make it where you can put a Watermark in, I know you could just make a text box and bla bla bla... but in this idea, no one can delete it, for you would make a password for the text box, so anyone wanting to edit/remove the Watermark can't, because they don't know the password!

I'm not a programmer so this could be tricky to program, but it would really make Musescore stand more out, even among the programs you PAY for.

So I thank all the people who have gotten Musescore to where it is now! because this program is in my opinion, the easiest and nicest program to use. Which I have tried using Sibelius and Finale, but they just don't feel nice to work in :)

(I have not searched to see if anyone has though of this exact idea, but if someone has I will use this as just a second voice :D)

And let me know what you think!
