I realize now (now that the implications of Carl's recent posted
plugin example have had a chance to cook in the ol' subconscious) that
a $self->parent->value call gives me the value of the data.  I think I
saw something that adds an element after a given element, so I'll see
if I can make a src element in my plugin using that data and add it in
there.  (Up to now my use of FormFu has been about 95%
configuration-only, which I think is a great testament to how much
"just works").

Anyway, just wanted to let everyone know I think I've found my way on this.
