It can be done, you just need to wrap your head around the possible solutions instead of the "perfect" solution you'd like to use Flash doesn't give you a way to transfer a movie clip from one running SWF to another so need to find a solution that Flash will let you get away with. There are two that I can think of... (1) you can import the SWFs to your library as movie clips OR (2) you can leave them on disk and load them by name. Either way the receiver is doing all the heavy lifting and the sender is just telling it which asset you'd like it to load and where it should find it. With the first solution the receiver has to have all the SWFs inside it (can make for a heavy SWF). With the second solution you don't need to modify your receiver every time you want/have to change one of the SWFs that needs to be loaded.
