All graphics related file saving stuff should go into fpl.
If something is not graphical but saving/loading, then it should go to io.
Personally me, I don't see the usefulness of developing very active
interaction/controlling capabilities for different external programs
such as opendx.

Sorry for being late in doing some corrections.
