Abstract
Unstructured overlay networks are a key component of many peer-to-peer systems. These overlays exhibit a set of interesting properties that derive from their inherent randomness. In this fast abstract we briefly discuss the key aspects that need to be considered when attempting to bias the structure of unstructured networks, such that it becomes possible to improve the efficiency of applications and services executed at the top level, without impairing the correctness of the overlay.
