Dear experts, and friends
I am going to do some protection of a kind of content files those are in format of my own. and i wanna do some thing like forward lock or separate delivery in order to prevent illegal copy of the content.
but now our design of the delivery way is not in online download, at lease in initial phase. We wanna people download our files in various ways, and the most widely used should be PC transferring like IrDA or bluetooth. but the content can not be copied from the phone.

Now my question is , does OMA DRM support offline protection. Meaning i can make a DRM file and only the allowed device, the specific one by paid user, can read the content. Copying without right permission and/or forwarding it is not valid.

THanks in advance.
