Since the original papers of Dre ll-Levy-Yan\, \; there has been a desire to unite the process of produ ction of hadrons in the final state to the process of probing the structur e of a hadronic initial state. Specifically\, one wants to relate the proc ess of single inclusive annihilation (SIA) to deep in-elastic scattering ( DIS) via crossing and analyticity. It has long been known that any straigh tforward relation between the two processes fails\, however\, pursuing thi s relation has lead to a deeper and richer connection between SIA and DIS\ , now known as the space-time reciprocity relation (arXiv hep-th/0612247). I shall give an introduction to this space-time reciprocity relation\, an d argue that the relationship is a consequence of the deeper connection be tween final and initial state dynamics governed by an underlying conformal symmetry which maps between the two\, up-to anomalous terms which should cancel as regulators are removed\, but from which one is never free due to the initial conditions of the scaling evolution. As a consequence\, I wil l give a time-like BFKL equation that resums the soft region of the fragme ntation function of QCD\, which maps to the space-like BFKL equation that governs the soft region of the parton distribution function. Time permitti ng\, I will discuss both possible formal implications and phenomenological applications. This will be a blackboard talk.
