    <abstract>A hybrid migration-diffusion model would be of considerable interest. The synthesis of two dynamic spatial models has much appeal -- too often we unwittingly generate and extend models independently of other models even though they are describing very closely related processes. More specifically, it is clear that the diffusion of information is often undertaken by agents who are shifting locations. For example, firms relocate or establish branch plants; opinion leaders change their place of residence. Thus the spatial diffusion process is often doubly dynamic -- information is spread according to an information field operator, but from one time period to the next, the distribution of the population (both knowers and non-knowers) is itself changing. On the face of it, diffusion processes of this type would appear to be highly relevant in a regional development context. This note represents a first crude attempt to model such systems.</abstract>
