The label is less important than how P2P fits in the collaborative computing fabric

COMPUTE MODEL

(Ways to architect the solution)

What people want

What technology can make possible now and in the future

DEPLOYMENT MODEL

(Ways to implement the solution)

USAGE MODEL

(What it does; how it behaves)

Ask in what ways people wish to collaborate; employ P2P where appropriate – it’s not all or nothing
