Abstract: An organization tree comprises nodes which represent different groups within an organization. The nodes are associated with users and devices in the organization. When a user requests an ownership voucher to install a device, the request is validated before an ownership voucher is generated. The validation includes at least verifying that the node the user is associated with is either the same node as the node of the device or is an ancestor node of the device.

Abstract: A system and method of managing unavailable items in shared screen data which provides access to modified screen data substantially simultaneously. The system includes a first computer including a display for displaying a screen containing items from screen data including modified screen data during a transaction. The modified screen data reflects that at least one of the items is unavailable. The first computer shares the screen data with a second computer. The first computer is also for displaying an indication that the at least one item is unavailable substantially simultaneously following modification of the screen data and upon selection of the at least one item at one of the first and second computers.
