Passing Pointers in ROS msgs on a Nodelet

I have image capture hardware that places images from an HD camera directly into memory and returns a pointer to me. I have no control over that memory location.

I would like to advertise the image's location to other nodelets I have running on the same process without copying the image data as you would in a normal ROS message.

Is there a standard or best practice in ROS for how to deal with this situation?
