Dragging nodes of a formatting graph

I want to use clim:formatting-graph-from-root to layout an *initial*
version of a graph.  Then, I want the user to be able to drag graph
nodes to a desired position, and redraw the node and connecting
links at the new position.  I also want to be able to capture the
position of each graph node so that I can write an external
representation of the graph and redraw it at a later time (possibly in
another Lisp session).

Has anyone done anything like this beast?  Does anyone have any
suggestions on how to approach this?  Is this going to be mega-hard?
