That thing that I am trying to explain is that if you actually
attempt to implement the functionality in the 2-point list, 
and try to use it in a distributed, multi-user application,
you would discover, sooner or later, that you need additional
functionality, above and beyond what libgda does today.  However,
after implementing all of these whiz-bang, multi-user, distributed
features, you would still have a 2-point sytem: something that
copies data between objects and other sources.  We do not yet have 
this 2-point sytem.
