Craig,
	I agree with you, and, while there is a history of language  
instruction that has structured our usage, I see a natural arch in  
our common usage of verbs that moves from intention with the  
infinitive form through the consideration of action depending on  
different conditions to the realization of the act as it becomes part  
of being, history, and a perfected quality.  In considering the  
probability of our intentions coming to fruition, can helps us  
consider our ability to carry them out, will focuses on the force of  
our intention, and shall addresses a sense of obligation created by  
circumstances around us.  Could, would, and should focus more on the  
situations that might have an effect upon what happens.  These usages  
serve our need to allow our imaginations to grapple with our  
intentions over time in order to help us realize who we want to be in  
this world.
	Given the limited number of words we can bring to this task, there  
will be multiple purposes served by these terms, giving language the  
strength and flexibility that comes from being ambiguous and  
connected to different frameworks.  But, for teaching grammar as a  
tool that empowers us to take action, I like seeing shall as turning  
our attention to outside forces that may affect our choices.
