Rolf, a few comments interspersed below, and more to come after I 
synthesize what the responses have been to these questions.

I'm willing to take this on as a challenge.

The challenge here would be providing anything other than a purely 
atom-by-atom selection. But would the equivalent be to trace the 
selection sets and, through that, be able to provide a script of the 
selections in order? Might be a bit lengthy, but it could provide the 
current selection automatically -- sort of a "selectionHistory" idea?

What if it just reproduced the exact script history, say, from the 
most recent load? (One would assume there are no loops.)
