taken from the book.... As noted above, response.download should be used to retrieve files stored via an upload field. response.stream can be used in other cases, such as returning a temporary file or StringIO object created by the controller. If attachment is True, the Content-Disposition header will be set to "attachment", and if filename is also provided, it will be added to the Content-Disposition header as well (but only when attachment is True). If not already included in response.headers, the following response headers will be set automatically: Content-Type, Content-Length, Cache-Control, Pragma, and Last-Modified (the latter three are set to allow browser caching of the file). To override any of these automatic header settings, simply set them in response.headers before calling response.stream.
So, you can use a StringIO instance to stream.... it **should** work with your blob contents.
