Hoi,
While I do agree that it is good to have the data in many places and, the Internet Archive on its own moves it to several places as well. Many of us have seen the IA servers at the Library of Alexandria.
While it is ok to find a use for the data at the IA, I would like us to concentrate first and foremost on how we can make better use of the media that is in Commons itself. How we can open it up to more use. Make Commons more accessable.
Do realise that when there is a good use for all the data that is in the IA, the same use and more could be made with the larger amount of data that is in Commons itself.
