Abstract: A method of managing data objects at a remote computing system is disclosed. The method includes receiving a request to provide a recipient associated with a recipient computing device with access to a data object, providing an identifier that references the data object, receiving a request for the data object from the recipient, and providing the recipient with access to the data object based on one or more characteristics of the recipient computing device.

Abstract: Active forms are intended to replace paper forms to increase the efficiency of workflow within an organization. In addition to replacing paper forms, the basic nature of active forms makes them well suited for use in systems that encompass multiple organizations. The invention consists of improved methods and systems using active forms, particularly among multiple organizations and with mobile computing devices.

Abstract: A system with an integrated user interface that provides a unified view of heterogeneous services via heterogeneous network nodes connected to heterogeneous networks. Access to services is provided without the need for installation of service-specific software on network nodes. Services that can be provided at multiple locations are performed at a location selected by the system based on the user's location. The system can update user preferences dynamically based on the user's history of service requests via the integrated user interface. The system can merge the preferences of multiple users for cases when multiple users all are impacted by the same preference.
