Study of the transiting and infalling bodies in the Beta Pictoris and other systems provide a probe of the composition of the planetesimals associated with the infall features, the presence of planetary perturbers in the system, and system architecture. Ultimately these provide a probe of processes which are thought to have delivered organics and water to the Habitable Zone and a young Earth. In this talk I will review what we know of the bodies in the Beta Pictoris Moving Group, 49 Cet, and Phi Leo, and the potential for extending these studies to FGKM stars.
