Abstract: A computing device includes an interface configured to communicate with a second computing device, a memory configured to store a first copy of a file that is synchronized with a second copy of the file stored at the second computing device, and a processor. The processor is configured, in response to receiving an update to the file while the interface is unable to communicate with the second computing device, to access versioning management data indicating synchronization settings associated with each of a plurality of files that includes the file. The processor is configured to, conditioned on determining that the versioning management data indicates a first synchronization setting associated with the file, write the update to the first copy, and conditioned on determining that the versioning management data indicates a second synchronization setting associated with the file, refrain from writing the update to the first copy.

Abstract: Systems and methods for trusted mobile communications are described. A network system provisions a mobile client system with a collection of security parameters on a per application basis and a per device basis. The airplane system provides access to the mobile client system based on the established chain of trust without previously having information about the mobile client system even when the mobile client system and the airplane system are offline with respect to the network system.

Abstract: A database of objects is distributed between a server computer and multiple client computers as an object oriented virtual world environment (VWE) with multimedia presentation features. A primary database is maintained on the server and includes at least one entry for each object disposed within the VWE. In one implementation a presentation virtual world environment has a multi-user virtual presentation room object (ShowRoom) in which presentation or information element objects (ShowItems) are presented from a server to multiple viewers at multiple client computers. The presentation room object and presentation element objects are global objects in that they are provided from server to client computers as part of a presentation VWE. The presentation element objects provide a model representing a presentation in the presentation VWE.
