Re: [slightly OT] File protection from copying

["Lech Rzedzicki" <xchaotic -at- gmail -dot- com>]

Unfortunately, yes you are being naive - there's always a way.

On top of that you alienate and make it difficult for the very users
that are paying you money, whereas a 'pirate' will make his own DRM
-free copy.

Compare the usage of a typical XVID from a torrent website vs Apple
Movie rental:

You download a 700MB high quality file for free, watch it whenever you
want, keep for however long you want, download in any country, store
on on disk, stream to the other computer, it all works. The movies are
available on the sam day they're screened in cinemas.

versus

Pay $5 or so dollars for the movie, pay for AppleTV, pay for more
bandwith needed,press play, it doesn't work because your HDMI doesn't
recognize this a s legitimate, manage to to go around it by removing
all your films from Amazon, pres play, then you have to go to bed and
after 24hrs it disappears and you have to buy it again. The movies are
available about a year from cinema premiere. That is assuming that you
live in US, because it doesn't work anywhere else.

And that's the best online movie rental service there is so far.

So sorry for the off-topic rant, but why on earth would anyone want to
do the latter?

Now apply this to your PDF scenario and think if your potential users
really need to go through this.
