5.10. Conclusion

The NetStream and Stream classes are the core classes for organizing and moving large amounts of data back and forth between Flash and FlashCom. In conjunction with the SharedObject class, the NetStream and Stream classes provide an amazing wealth of options for delivering real-time or recorded audio, video, and ActionScript data. In the remaining chapters, streams will be used for video conferencing, to play chat histories, and to record and play back application eventsyou'll find them everywhere. After a while, using them whenever you need to move data will become second nature.
