A do a lot of experimenting with Geographic data and WorldWind. I met Ben at the FOSS4G in Sydney and he demonstrated the GeoSciML based core library demo. I wanted to move some of the tasks such as graphing and core image analysis from the server side to the client side to allow heavier user loads on the server and minimize retransmissions, allowing users to do further client side operations on cached data without explicitly having to download core images. Of course to do all this the user system needs to have generous GPU and CPU grunt, but that is cheap these days. The user side transfer helps scale the system on peak loads, JNLP based deployment help keep all user instances of analysis code in sync much like a browser based application currently in use.
