title: Using Paperclip to direct upload files to S3
body: <p>so I've got paperclip set up with uploadify to upload things to S3.  I have made my setup so that stuff gets loaded directly to S3 and then when it's done I post to my webserver the results...</p>
  
  <p>All I get back is the file name and size.  am I supposed to build my own processor or before_post_process method to "download" the file from S3 in order to process it? or am I missing something and uploadify should have provided me a stream with the file inside it after it was done posting to S3?</p>
  
  <p>How do you guys go about direct uploads to S3 and then notifying your paperclip backed model?  Do you have to pull files from the server and do post-processing on them or will paperclip handle all of that? </p>
