Method and apparatus for restricted run-time environment with dynamic user context

A computer system interface comprising:

• a server;
• a local machine connected with said server, the local machine includes a first set of system files;
• a run-time environment provider for providing a restricted run-time environment in said local machine, the restricted run-time environment includes a second set of system files, wherein the second set of system files is accessible from an application performing processes in the restricted run-time environment the restricted run-time environment also includes an isolation unit for isolating the first set of system files from the restricted run-time environment;
• and
• a context generator for providing a selected one of a plurality of available local user contexts dynamically for use with said restricted run-time environment, while said restricted run-time environment is being used, wherein the plurality of available local user contexts are stored on the computer system and the selected local user context is downloaded from the computer system to the restricted run-time environment.

A computer system comprising:

• a network;
• a first server for providing state and computational services;
• a client connected with said first server via said network;
• a first set of system files included in said first server;
• a restricted run-time environment isolated from said first set of system files wherein said restricted run-time environment are located within said client and wherein said restricted run-time environment includes a second set of system files, wherein said second set of system files is accessible from an application performing processes in the restricted run-time environment, said restricted run-time environment is isolated from said first set of system files;
• a selected one of a plurality of local user contexts dynamically configured to be used with said restricted run-time environment, while said restricted run-time environment is being used, wherein the plurality of available local user contexts are stored on the computer system and the selected local user context is downloaded from the computer system to the restricted run-time environment;
• and
• a user interface initiated using said local user context.
