During 12 of the last 30 days, the CMS experiment has moved more than 80TB a day
across the roughly 40 sites on EGEE and OSG. Large volume data movement has
clearly become a routine operation.

We will reflect upon the successes as well as remaining challenges for large scale data movement for a community of
a couple thousand scientists. Special emphasis will be put on technological as well as sociological obstacles that
still make large scale data movement a challenge, and the corresponding risks to the CMS computing model.
