[gridcpr-wg] Use Cases for Grid Checkpoint and Recovery - Comments

[Paul Stodghill]

I apologize, but I still don't understand what you are suggesting. Do 
you think that there is a particular storage model that is implied by 
the use-cases? Can you give an example of the sorts of changes that you 
think should be made to the use-case doc?

Thanks for your comment.
