  We study noise and transport in multiterminal diffusive conductors. Using a
Boltzmann-Langevin equation approach we reduce the calculation of shot-noise
correlators to the solution of diffusion equations. Within this approach we
prove the universality of shot-noise in multiterminal diffusive conductors of
arbitrary shape and dimension for purely elastic scattering as well as for hot
electrons. We show that shot-noise in multiterminal conductors is a non-local
quantity and that exchange effects can occur in the absence of quantum phase
coherence even at zero electron temperature. It is also shown that the exchange
effect measured in one contact is always negative -- in agreement with the
Pauli principle. We discuss a new phenomenon in which current noise is induced
by thermal transport. We propose a possible experiment to measure locally the
effective noise temperature. Concrete numbers for shot-noise are given that can
be tested experimentally.
