I got around this in my game by allowing the player to change the layer he is drawn on. If he's noted as 'layer 2', he's drawn between 2 and 3. If he's on 'layer 4', he'd drawn between 4 and 5.

The Z variable in ZC, I imagine, will allow for some LttP style layer effects, possibly affecting how the player interacts with layers above 2.

Regarding your quote, BH4, layering isn't a problem. If I want an item on layer 3, I just place it on the screen that corresponds to that layer. This isn't necessarily the way it's done in ZC, but there's as chance it might be in the future.
