make connections to other servers in the cluster and can exchange events (in a limited fashion). This is different than Liz's project wherein servers share an oid space and one can interchangably work with distributed objects from any server. This package provides a means by which certain services (by default, presence and chat) can be communicated between servers to allow communication between players scattered around a bunch of otherwise independent server instances. This is less general purpose but also less likely to encourage people to write code that tightly couples multiple servers and then falls over because it generates gobs of network traffic as events are flung willy nilly behind the scenes. git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@4238 542714f4-19e9-0310-aa3c-eee0fc999fb1
