Lightstreamer is a server-side application, not intended for the final user, but for a company or a service-provider that needs to push real-time data to their final users. To use Lightstreamer, you need to install the server and develop a custom Adapter (usually in Java or .NET programming languages) to connect to your data feed.
So I'm not sure Lightstreamer is what you are looking for.
