Off-Site Storage

Hi Guys

Im hoping my WPMU/Buddypress community will grow massive. Problem i might have is disk space. Currently the default per user is 50MB but that is not alot.

Would be great if there was a plugin or something that allowed users to easily storage their media in another storage provider, eg: amazon s3, azure, etc

now, i know they can manually do this and just link the images etc, but would be great if this was integrated into the admin area.

better yet, would be great if this was free, and supporters could use normal storage....know what i mean?
