The "viewport.image.render" rpc call includes the browser viewport size as a parameter, and the server-side peer window should resize itself so that you get the correct image in your browser. However, if the remote display is configured to have a maximum size of 640 x 480, then I do not believe there is any way to request a larger image from the client side. Perhaps someone else knows otherwise though.
