  abstract =	 {In many multiagent systems, agents are not able to
                  freely interact with each other or with a
                  centralized mechanism. They may be limited in their
                  interactions by cost or by the inherent structure of
                  the system. Using a combinatorial auction
                  application as motivation, we study the impact of
                  interaction costs and structure on the strategic
                  behaviour of self-interested agents. We present a
                  particular model of costly agent-interaction, and
                  argue that self-interested agents may wish to
                  coordinate their actions with their neighbours so as
                  to reduce their individual costs. We highlight the
                  issues that arise in such a setting, propose a
                  cost-sharing mechanism that agents can use, and
                  discuss group coordination procedures. Experimental
                  work validates our model.},
