| New data types (for example new video compression formats etc.) can be supported in Java even if HotJava browsers are not aware of such new formats. |
| The data processing software needs to be packaged in terms of Java classes and provided together with the data access itself. |
| HotJava downloads and dynamically installs the processing software first, and then proceeds with handling the data. |
| In a similar way, the model can handle a variety of custom communication protocols, e.g. proprietary extensions of HTTP including some special security issues. The protocol handler needs to be provided as a Java package together with the protocol. It will be dynamically installed by HotJava and then used to handle the message transfer. |
