My primary concern is that gstreamer would introduce another image
stream framework within the ROS image pipeline. That seems
architecturally undesirable. In my mind, what we want is more
analogous to the dc1394src gstreamer plugin Trevor mentioned.

I could be wrong about that and can probably be convinced otherwise.
But, that is my current thinking. We already have two good ROS drivers
based on libdc1394. I am more inclined to pursue those options.

Comments and feedback are (always) welcome...
