This seems more of a concept item than a real life implementation but if your bored and wish to check it out theres a program available to back this one up.

https://sourceforge.net/project/showfiles.php?group_id=96735&package_id=198839&release_id=435520At its very core, everything within an “OFF Cache” is a block – a uniformly sized file of 128KB. This file is ownerless; it does not represent nor is a derived work of the original file from which it was spawned. Since all blocks within OFF are uniform, they can be coupled in an infinite number of ways to produce an infinite number of files.
Abstraction
This concept is akin to a bucket of building blocks of uniform size, building blocks that cannot be owned by any one person or persons.
While it is true that certain representations derived from these building blocks – the Mona Lisa or a wholly unique design – may be “owned” by one person, the actual blocks themselves cannot be owned. Thus, a representation may be depreciated – taking a sledgehammer to the aforementioned Mona Lisa – and their constituent parts may be traded and shared freely among others. This is no way illegal.
However, given the correct “recipe,” you may be able to reconstruct an owned representation from the blocks someone gives you. The “recipe” in this case are known as descriptor blocks. However, since descriptor blocks are in no way different from any other block in the cache, it is impossible to know if any block given to you may represent a descriptor block as opposed to representing another design. In fact, it is highly possible that a given block will represent BOTH a descriptor block AND another competing design. This is multiple use encoding.
I see some sort of legal challenge in the wind but the combining of two seperate files to create a new third file that is not a copyrighted representation is legal to share and exchange, the beauty of this system is in putting the blocks back together , do it wrong and any file can be created, the possibilities are near infinite.
Of course this will be of no help to those exchanging files as many do at present on our network but its a fight back against those who claim that all data passing across p2p nets is copyrighted.
