Emerald objects can move from one node to another. So, for example, if an object on machine X wants to perform computation using data on some remote machine Y, the object can move to Y and have (fast, local) access to Y's data, then move back to X when it is done. So the computations themselves are mobile. This required some cleverness in the implementation, because a process's stack might even be split between multiple machines (I might be remembering that wrong).
