One thin is if you are doing all this work to re-vamp the layers, why limit 
them to 20?  Maybe only the first 20 in the list get a button on the header, 
(so you should be able to move them up and down).

Objects on more than one layer pose a problem as to just using an ID code.  
Perhaps a layer should just be a linked list of Object ID's with a flag that 
define what attributes to get from which layer.  ie; an object's first layer 
is it's Primary Layer and it gets all attributes that you can't really just 
OR together, like draw color/mode.  Other layers assigned would be secondary 
and just OR the visible/render/lock flags together.

Of course that system poses all sorts of UI issues, too.  If you try to edit 
an object and find it's locked by one of the 39 layers it's a member of, 
which layer do you go to to unlock it?

I think the Blender concept of Layers is so radically different from 
other apps that trying to borrow from their Layer manager is a just 
asking for trouble.
