The "stream" file is a generic container that can hold any number of chunk types. The [[https://github.com/trapexit/3do-devkit/tree/master/examples/3dosdk/Toolkit 1.5/Streaming/2p1|DataStream library]] is a pretty open and generic library to allow arbitrary data types to be streamed via a consistent framework. Each type have a "subscriber" that handles the data chunks.
