Browser based event information delivery mechanism using application resident on removable storage device

At a client, a first application is executed to identify event information with respect to events that occur at the client, including events associated with execution of one or more other applications resident on the client. The first application communicates with a second application, also executing on the client, to transmit the event information to a communications network, wherein the second application and not the first application is in communication with the communications network. In some embodiments, the second application is a browser application. Optionally, the first application installs a browser loadable object in the browser application, and the browser loadable object registers callback information with the first application. Later, the first application uses the callback information to communicate a network request to the browser loadable object.
