Two ArrayCollections pointing at the same source should be working with references to the items, so you shouldn't need to "transfer data". I believe that if you slice the source array and wrap it with an ArrayCollection, then changes to the item objects via the AC API will actually apply to the base array. Test that to be sure.
If that does not work, and users can update the data through the restricted AC, then you might have to explicitly update the real source.
