Abstract: Improved techniques for real-time collaborative development in an authoring system, especially suited for the production of multimedia applications and games, are described. In an exemplary embodiment, collaborative live development involves: (i) loading digital resources of a structured binary format in a host device that manages synchronization and versioning, (ii) establishing a communication session between the host device and a client device, (iii) synchronizing digital files of a structured binary format between the client device and the host device using devices similar to Source Control Management systems, and (iv) incorporating any resource changes in the Live Programming execution environment in a non-intrusive manner on the basis of predefined criteria.
