For someone who has already decided that Blender's object
architecture is a complete mess and totally inadequate, you 
seem to have a lot of questions about the basic data structures.  
Not to mention a total unfamiliarity with linked lists.

None of which means that these are not good questions, though.
You might want to find a good book on data structures.  It
will explain lists and trees and all sorts of other goodies.
