Sharing library assets between 2 or more swf?

programming flash
1

Since I can access the library assets from external class, I have a question :

  1. Is it possible to use any of library assets of one movie into another? Let’s say in my movie A, I have McA1 movieclip in the library. Is it possible to access/display/addChild McA1 in movie B?

  2. If there’s a case that Movie B is loaded into Movie A - does all the library from Movie B will be inherited into movie A - vice versa - so it makes them accessible?

  3. If the answer of 1, and 2, is no and no, is there any work around to make any library asset accessible accross the board? Is this what so called runtime sharing? Do you have any resource that I can refer to?

Cheers
