Robert:

So far great work.  It's overall working very well.

That being said, I have a pair of questions:
#1 I'm trying to use the camera cape with the board, and I get the 
following error message when I try to read from it using openCV: 
VIDIOC_REQBUFS: Cannot allocate memory.  I believe this has something to do 
with the dd for the camera, but I'm not sure if it is something that 
requires mods to the dd or just a change in configuration.
#2 I'm assuming this is by design, but when i try to read from the camera 
using gstreamer, I get a package not found error.  It seems as if gstreamer 
isn't in this package, yet I aloso run into problems when I try to do an 
apt-get in that it can not be located.  This may very well be by design and 
I just haven't overcome the issues.

Thanks again for your hard work on this codebase.

Walt
