if i have a playlist in one part of the tree and the same playlist in another part of the tree

I'm going to break the habit of a lifetime. This feature won't be new in v1.1.

If I understand what you're asking, it already does this in v1.0x. Simply create the REM playlist. Put some stuff in it. Now, copy the REM playlist (not the contents) to another part of the playlist tree.

Now modify either "copy" of REM -- you'll find that it's the same playlist.
