Hi Alex
In order to apply DRM, you need to have a license for a DRM scheme,
either that or create one yourself. The mp4 container, which is what
iTunes uses, is capable of handling just about any stream including
any drm you may wish to use. Apple does not provide any way for the
users to DRM their content, and there's no such thing as an open
source DRM scheme--after all, that would hardly make any sense would
it? Apple licenses the Fair Play drm scheme, currently they use
version 3, it is not something they develop, and they cannot provide
this functionality to the end user without breaking their agreement.
Remember, DRM isn't going to protect your content. If someone wants it
badly enough, they will get it, and it generally provides restrictions
and inconveniences only to those who acquire the content under your
terms--in other words, the hackers are only inconvenienced for a bit,
and legitimate users are inconvenienced all the time. Also bare in
mind that this will lock out some operating systems or platforms.
Linux, for example, has no DRM support whatsoever, so if you want
other platforms besides Mac and/or Windows to be able to play your
content you need to stay away from DRM altogether or, of course,
develop an application or plugin for those platforms that can handle
your DRM. And then, of course, there's portable devices such as iPods...
You might want to consider another approach, i.e. perhaps make it a
streaming content that is only available for a certain length of time.
This would mean you wouldn't need a drm license, or need to create a
drm encryption scheme yourself, you could handle distributing the
streaming via php or some other web language.
Other than that, you'll have to look into various DRMs, and what their
costs are.

Hi,
All,
I want to put DRM on some content I have made so that it can be
played only for a specified period of time. Say you download it. I
want it to be playable between May the 1st and June the first. How
do you do this on the Mac? Does any utility work with Voiceover?
Thanks foer lisetneing,
Alex,
The major difference between a thing that might go wrong and a
thing that cannot possibly go wrong is that when a thing that cannot
possibly go wrong goes wrong it usually turns out to be impossible to
get at or repair.
