It would be less evil if the storage exposed extra capabilities to the 
application though _p_ attributes:

class SimpleFileData:

     def __init__(self, bytes):
         self.bytes = bytes

     _p_path_to_data = None

     def send(self, RESPONSE):
         if self _p_path_to_data in not None:
             # Hurrah! a gift from our storage
             bytes = open(self._p_path_to_data, 'rb').read()
             RESPONSE.write(bytes)
         else:
             RESPONSE.write(self.bytes)
