No, that's a good start.  Enumerated space.  Is that addressing 
by name or position?  Are the points on the curve or is the curve 
a boundary for the points inside the circumscribed space?

Depends on the space.

Consider the integers mod k as a one dimensional space (ie. a closed,
discrete, curve). Every point in the space has a successor (and no two 
points have the same successor), so it has no boundaries, yet we can 
enumerate all the points in the space in O(k) time.

I presume that's not quite what you meant tho' ...
