Not to be too cute, but who uses just one computer 
  anymore ...
TJ, I appreciate your direct acknowlegement of this 
  situation. It's
something that people should know about in advance (if 
  possible) of
assuming/attempting otherwise.
I sincerely hope that an 
  appropriately high priority will be given to
enhancing the AB architecture 
  so that creational work done on different
machines at different times 
  (charts made, code written, layouts created,
etc. etc.) can be easily 
  cr0ss-copied to be available identically on
each machine, with no problems 
  being created 
  thereby.
