Abstract: A technique for executing a segmented virtual machine (VM) is disclosed. A plurality of core VM's are implemented in a common core space. Each core VM is associated with a shell VM. Resources of the core space are allocated among the core VM's. A core VM is associated with a shell VM configured to perform shell VM functions and communicate with the core VM. VM internal execution functionality is performed on the core VM. The shell VM may be bypassed to communicate with an external application.

Abstract: In one embodiment of the invention, browser plug-in includes a personal content tunnel (PCT) object processor, a PCT resolution module, and a server interface. The PCT object processor processes a PCT object returned by a content server in response to a request from a client. The PCT object contains PCT information. The PCT resolution module resolves a service uniform resource identifier (URI) using the PCT information according to a PCT resolution protocol. The service URI identifies a PCT resolution server. The server interface receives a content URI and a PCT termination point resolved by the PCT resolution server.

Abstract: An operating environment for use on a computer system to provide operating system services to a user application running on the computer system. The computer system includes a network connecting the computer system to at least one other computer system. The user application generates operating system commands requiring access to the network, and commands requiring operating system actions that do not access the network. An operating environment according to the present invention includes a network server for accessing the network, a non-network server for executing operating system commands not requiring network services, and an emulation library for receiving the operating system commands generated by the user application.
