Molecular Rights Management
I'll have more to say about this soon, but I just want to toss the idea out to the noösphere and make it visible.
Molecular Rights Management refers to the panoply of technologies employed to prevent the unrestricted reproduction of the products of molecular scale (atomically-precise, nano-fabricated) manufacturing technologies. The source concept for the term is digital rights management, technologies employed to prevent the unrestricted reproduction of digital products. As of yet, no actual molecular rights management technologies exist.
MRM is likely to emerge for two primary reasons: the continued need for intellectual property controls, so as to prevent a wave "napster fabbing;" and the need for security to prevent the production of controlled goods ("assault rifles," figuratively or literally).
MRM could reside in the design media (the CAD files and the like), such as with single-execution licenses, digital watermarks, and so forth.
MRM could reside in the production hardware (the "nanofactory"), such as with systems that "store" all designs online (no local storage), blacklist systems that a nanofactory would check an input design against, smart systems that recognize disallowed designs as they are being made, even in disconnected parts, and so forth.
MRM could reside in the network, with agents that check the designs loaded in a nanofactory for proper licensing information.
Given that the final results of a nanomanufactured product can, in principle, be used without any need to connect back to the original fabber or design, the impact of MRM on end-users is likely to be less onerous than the impact of DRM has been on the users of digital media. Couple that to the safety/security aspects, and it seems to me that MRM is likely to be broadly tolerated, and potentially even accepted.
