I don't think that refactoring this out of the current space library
would be that difficult, although, the api's would be different.  Also,
if we were going to make changes like this, I think that I wouldn't
focus on backwards compatibility.

True enough.  This is something that we have been thinking about for
quite some time.  The main dilemma has been the best way to approach
this.  For many of us, aspect oriented programming seems the way to go,
but unfortunately this is not practical.  Interfaces seems like a good
way to approach it, but I suppose what has been really delaying us has
been the task of determining what common semantics exist within agent
types.

I think that this is a very good point, though.
