Here's how to save your PDF as a string in memory.

 buf = StringIO.StringIO()

  c = Canvas(buf)


  #do your drawing here


  c.save()    #PDF file is written into the buffer at this point


  #extract contents as a byte string
  buf.reset()
  rawPdfFileContent = buf.read()

You then pass this to the response.   If it was Django, I could write
to the response object (which is file-like), so I could do this and
cut out the StringIO...

  response.setContentType('application/pdf')
  c = Canvas(response)
  ....
  c.save()
