I have just had a look at the Brockerage section on C3D and it seems that there will be more than one way for us to buy content from there(C3D). It will be up to the person selling there content how they wish to sell it, i.e they will be able to put it on the store in more than one format. If they use vue's vob format it will be encripted also it can be locked or unlocked (depending on which vue version), they can also put there content on the site in the more generic formats 3DS OBJ ect which will not be locked, it all depends on how they want there content used and the amount money they wish to make. Just a couple of observations.
