The document discusses various ways to exchange data between Flash and Joomla, including: 1. Using XML for data exchange by reading XML files into Flash or producing XML from Joomla using components, feeds, or directly querying the database. 2. Using web services like AMF, SOAP, and XML-RPC for bidirectional data exchange, with examples of projects that implement these in Flash and Joomla. 3. Future plans to build a Joomla component for menu syndication in XML and a Joomla SOAP plugin to further facilitate integration between the platforms.
