This is oddly close to what I think DRM ought to be: advisory, not enforcing. Remove the accountability aspect, not least because it's a farce that leaves the most recent honest party holding the bag, and you have my concept of an ideal DRM engine: provenance meta-tags that let you know what color your bits are, which you can use if it affects you or ignore if it doesn't, leaving no rights-holder the wiser no matter what course you take.
Accountability-oriented DRM, which prevents no action but forces your use of certain combinations of certain colors of bits into public record, would be prone to false positives. Pulled in some GPL code to a local build of 7-Zip? Chances are the other code doesn't have a GPL exception to allow linking against the non-Open unrar, so the resulting software likely may not be conveyed (in the GPLv3 sense) at all, but creating or using the resulting combined work won't infringe anyone's rights and shouldn't require you posting public notice that you have created such a combined work if you have no intent to convey it.
