After sending the above message, I realized that my original patch did not 
actually include anything to do with EmbeddedNetworkFile. :)  The attached 
patch shows how the EmbeddedNetworkFile helps begin to abstract the 
MainWindow away from the direct use of XML.  Sorry for the confusion.

This patch also helps underscore the ideas that 1) an intermediate NetworkFile 
base class could be useful (in addition to EmbeddedNetworkFile) and that 2) a 
NetworkStorageErr exception will be needed to completely hide the XML 
implementation details.  This patch works great, and it's a clear win from 
the perspectives of abstraction and encapsulation.  But it's not done.

Cheers,

Zach
