Nice technique, Booth, but it will bite you when you leave the green
screen.  The overhead of sending a data structure to and from the UI
server gets VERY costly, especially as the amount of data increases.  It
can actually be more efficient to simply send the keys and re-CHAIN when
needed.  It also helps reduce staleness issues.
 
As always, it's a business decision.
