Abstract: The invention provides in some aspects a digital data system that includes a first digital data device that, in order to transfer a digital media object to a second digital data device, transfers to that second digital data device a virtual machine embodying that digital media object. Those digital data devices may be, according to aspects of the invention, any of mainframe computers, minicomputers, workstations, desktop computers, portable computers, tablet computers, smart phones, personal digital assistants, eReaders, video consoles, movie players and other dedicated digital data devices.

Abstract: The invention provides, in some aspects, a digital commerce system that includes first and second digital data devices that are coupled with a server digital data processor via a network supporting at least intermittent communications therebetween. The server digital data processor is responsive to requests by owners/operators of those digital data devices for (i) selling or otherwise transferring ownership of or other rights in an object from an owner/operator of the first digital data device to an owner/operator of the second digital data device, and (ii) transferring any of credits and/or monetary funds (collectively, “funds”) from an owner/operator of the second digital data device to a charity designated by the owner/operator of the first digital data device.

Abstract: The invention provides in some aspects an improved method for transfer of digital media objects that includes storing a digital file on a first digital data device and migrating that digital file to a second digital data device by repeating a plurality of times the steps of: (i) transferring to a second digital data a respective piece of the digital file, (ii) storing that respective piece of the digital file on the second digital data device. The foregoing are effected so that no respective piece of the digital file is concurrently stored on the first and second digital data devices and/or, more generally, so that any same portion of the digital file that is concurrently stored on the first and second digital data devices comprises not more than an insubstantial amount of the digital data file. Methods and apparatus according to the invention can be used for the (re)sale, lending, streaming or other transfer of digital music, digital books and other digital media objects.

Abstract: The invention provide systems and methods for management of digital media objects, comprising first and second client digital data processors (e.g., personal (or private) computers, laptops, dedicated music devices, electronic book readers, and so forth) that are in communications coupling with one or more stores (e.g, dedicated disk drives, flash drives, cloud storage, etc.). At least one digital media object (DMO) or copy thereof is stored in one or more of those stores and is accessible by at least one of the first and second client digital data processors.

Abstract: The invention provides, in some aspects, a digital commerce system that includes a first digital data device, a second digital data device and a third digital data device, each of which is connected to a network that provides at least intermittent communications coupling between the second digital data device and each of the first and second digital data devices. Redirection logic executing on at least the second digital data device effects storage on the third digital data device of a digital media object downloaded from the first digital data device to the second digital data device. The redirection logic accomplishes that in such a manner that storage of the digital media object on the third digital data device is effected before storage of that digital media object on the second digital data device—if the digital media object is stored to the second digital data device at all.
