This may be related to the "naming of cameras" question I posted this morning.

The way I've been approaching this is to set the node name to the
camera name, so the topics become /left/camera/image_raw, etc. That's
fine with roslaunch, but less convenient with rosrun. This should
work:

 $ rosrun camera1394 camera1394 camera1394:=left

I am open to suggestions whether this naming scheme is good or bad. We
could make it run more like the wge100_node, with different cameras
started in different namespaces. As best I can tell, the topic names
are compatible, but the two drivers arrive at them via different
paths.
