If it's similar to the Starband service, the software they load also includes a proxy. Make sure you use it, as it can speed up the loading times on web pages. The one I saw would receive all the images and extra content back along with the main HTML page to cache, so it was there when the web browser would start asking for them as it parsed the HTML. That way, you don't see the nearly second lag time between request, html and image loading.
