video library

I have a client that wants me to develop an image and video library which I've already done with Drupal since the taxonomy among other things works very well. My challenge now is to handle the storage requirements. Initially we will need about 1TB and eventually about 2TB. Amazon S3 seemed like a great option, both cost effective and scalable. I just can't figure out how to have the system/modules store the images in my bucket rather than a directory on the server.
