I don't think Tom's post made it to the list.

> In anycase, Nick, I've been working on the problem of eliminating the spatial reference from the agent.  As I have written it, the only reference is in the constructor, and it is as an Object.  I handle all the casting in the aspect.  Basically, I introduce a method on the class called setWorld(Object world).  Beyond that, the code is completely free of any reference to the space.  I now have a method move(Point old, Point new) that handles the movement.

One concern is specialty spaces like heatspace.  This space has methods like diffuse that we cannot account for in the aspect(of course, I can for heatspace, but generally I cannot).  This would still require either a reference to the space or to be handled in the model.  I think.  If anyone has any thoughts, that would be cool.
