Undo Redo

I am working on a Swing (Netbeans) application, and need to provide
Undo/Redo support.  This seems like a pretty clear cross-cutting
concern, as it results in a great deal of code tangling and scattering.

I have seen a fair amount of information on Undo/Redo with regard to
aop.  Most of the examples seem rather trivial, however.  Has anyone on
this list implemented Undo/Redo via AOP?  If so, what were your
experiences with it, and would you do it that way again?
