System, device, method, and computer program and computer program products for providing communicating between devices having similar or dissimilar characteristics and facilitating seamless interoperability between them. Computer program software and methods of and systems and devices for sharing of content, applications, resources and control across similar and dissimilar permanently or intermittently connected electronic devices. Devices, systems, appliances, and the like communicating and/or interoperating within the framework provided. Social security interoperability model and method, such as Dart Social Security Interoperability, provide particularly method for forming webs of security between teams of intermittently connected devices. Foundation for social security is use of social synchronization to spread unique identifiers along with allowed access rights which travel transitively from device to device. Devices which have never communicated will find that they are part of team which are allowed to interoperate with certain access rights without need for further gathering permissions.
