A few quick things

1) I can use it with rviz.  Jack, I'll shoot you an email tomorrow with 
the rviz config that I use.  Remind me if I forget.

2) My driver started as a port from Player, but I've replaced and added 
a lot of functionality (e.g. Bayer filtering) with built-in libdc1394 
functions.

3) Jack, once you get into this, I might bend your ear to help me do the 
same for a unified Swissranger 3000/4000 driver.  I have a version that 
I expanded from Rasu's 3K driver that adds new functionality for 4K 
devices.   I also have a color camera/pointcloud registration node )with 
calibration utility) that would probably go in this stack (but could be 
used for stereo cameras).  I haven't looked around recently to see if 
others exist, but I don't remember seeing anything that worked in ros 
 >=0.9 several months back.
