Q1: How has SPIN evolved since the Shared Pathology Informatics Network?
A1: Beyond searching for discarded Human Tissue, SPIN has been used for Biosurveillance, General Clinical Research, and Resource Discovery.

Q2: Is SPIN a peer-to-peer topology or a hub-spoke topology?
A2: SPIN can support many network topologies concurrently in a single deployed system.
P2P models are often deployed when there are a limited number of institutions, at the expense that many routing table rules are needed.
The benefit of the pure p2p (fully meshed) topology is that no single institution is "super" and any node can go offline with 100% network tolerance.
Hub-Spoke Networks are commonly used when there are a larger number of institutions which have previous trust agreements.
Hub-spoke networks have the advantage that less network maintainable is required, at the expense that some institutions have greater responsibility.
