Try Fog (http://fog.io) -- you can open up a storage connection and
write directly to S3:

Creating the S3 item (new) after making connection and bucket:

file = bucket.files.create(
  :key => 'test_pdf.pdf',
  :body => pdf,
  :public => true
)

and the public URL is at:

file.public_url

Saving a new version of the S3 item:

file = bucket.files.get('test_pdf.pdf')
file.body = newpdf
file.save
