A first and second environment define parameters communicated between a first computer remotely controlling a second computer (a first remote session) and between the second computer remotely controlling the first computer (a second remote session), with each parameter defining an action associated with the first or second remote session. A first application, via a unidirectional communication with the first environment, modifies a first parameter, wherein the first parameter is extracted by a first interceptor (associated with the second computer) that, based on a look-up, executes a pre-defined action (different than the first parameter's associated action) affecting the first remote session. A second application, via a unidirectional communication with the second environment, modifies a second parameter, wherein the second parameter is extracted by a second interceptor (associated with the first computer) that, based on a look-up, executes a pre-defined action (different than the second parameter's associated action) affecting the second remote session.
