  This paper builds on earlier work, where the authors described Whittaker
modules for the Virasoro algebra. Using a framework of Batra and Mazorchuk, the
current paper investigates a category of Virasoro algebra modules that includes
Whittaker modules. Results in this paper include a classification of the simple
modules in the category and a description of certain induced modules that are a
natural generalization of simple Whittaker modules.
