    Abstract: Disclosed herein is a technique for enabling isolated processes executing within a web browser to distribute information to one another. The method can be implemented by a first process executing within the web browser, and include the steps of (1) receiving, from a child process executing within the web browser, a first request to subscribe to a topic, (2) in response to identifying that the child process is not subscribed to the topic: updating a topic map to indicate that the child process is subscribed to the topic, and (3) in response to identifying that the first process is associated with the parent process: issuing, to the parent process, a second request for the first process to subscribe to the topic. Also disclosed herein is a method for enabling a first process executing within a web browser to access services provided by other processes executing within the web browser.
