Accendia has released JNetStart 2.1, "a secure network class loader that enables the user to launch a Java Swing application deployed on a remote server without the need to install or download the application component files. JNetStart is unique in the granularity of the components downloaded in the startup process. Instead of application jar files, JNetStart loads classes and resources on the client machine. This makes large Swing applications instantly available to the user." JNetStart costs $495 per server.
