A capability is just a fancy name for a pointer in a machine that doesn't have enough address space to begin with. 2. The current hangup of capability machines is their unwillingness to do garbage collection. (Tracing, etc., that is.) 3. Lisp was the first capability machine. It is true that the objects are quite small in the original Lisps, but with newer Lisps having vectors, strings, objects, classes, flavors, and what have you, they have all the power of Hydras, 432's, etc.
