   * The mime types are 0-based so the first mime type is 
   * at index 0, the second at index 1 and so on.  The mime-type
   * at index 0 should be considered the "default" data type for the stream.
   * This assumes that the strings for the mime types are stored in the
   * AtkStreamableContent. Alternatively the G_CONST_RETURN could be removed
   * and the caller would be responsible for calling g_free() on the
   * returned value.

   * One possible implementation for this method is that it constructs the
   * content appropriate for the mime type and then creates a temporary
   * file containing the content, opens the file and then calls
   * g_io_channel_unix_new_fd().

 * Returns a string representing a URI in IETF standard format
 * (see http://www.ietf.org/rfc/rfc2396.txt) from which the object's content
 * may be streamed in the specified mime-type.
 * If mime_type is NULL, the URI for the default (and possibly only) mime-type is
 * returned.
 * returns NULL if the mime-type is not supported, or if no URI can be 
 * constructed.  Note that it is possible for get_uri to return NULL but for
 * get_stream to work nonetheless, since not all GIOChannels connect to URIs.
