Author here - Yes that is exactly what it does. I'll compile it for the Mac later today and load it on the Scrumdog.app website. Thanks for your comments.
Another way of looking at at:
Where own data-center cost gets to high it might be due to lack of responsibility to act or inability to manage.
A company then have two options:
(a) replace/pressure top/middle management to get costs down and processes streamlined or, (b) move to the cloud. Its easier (and possibly good for your resume) to move to the cloud and then a few yours later -- decide again.
So moving to the cloud is sometimes an indicator of an inflexible/stale/mature company.
