The program of understanding inverse-power law corrections to event shapes and energy flow observables in e<sup>+</sup>e<sup>−</sup> annihilation to two jets and DIS (1+1) jets has been a significant success of QCD phenomenology over the last decade. The important extension of this program to similar observables in hadron collisions is not straightforward, being obscured by both conceptual and technical issues. In this paper we shed light on some of these issues by providing an estimate of power corrections to the inter-jet E<sub>t</sub> flow distribution in hadron collisions using the techniques that were employed in the e<sup>+</sup>e<sup>−</sup> annihilation and DIS cases.
