Hi Friends, I did a small PoC on Flex 2.0.1 modules and found it straight forward simple. You can create Flex project with <mx:Module> tag and then this project gets compiled into swf and then these compiled swfs can be invoked/loaded by any application at runtime. Loading and unloading is simple. Its analogous to dlls or .jar files, compiled swfs.Queries are welcome here.
