So the question is what licensing did your company purchase, basic or extended ?
Becasue if you only have basic, then your correct that you cannot legally run the DRM.
If on the other hand you have extended, then you can as part of the new licensing scheme.
I can tell you from experience that doing DRM without the DRM license is a real challenge!
It probably can be done, but practically everybody relies upon the DRM module in one way
or another to make this work right.
If you have some more specific questions, we might be able to provide you with some guidance, but your initial query is too broad to really answer at this point.
