It will not be in the diamondback camera_drivers stack. I have had no
time to work on it because of pushing that camera_drivers release.
After diamondback has its final release will be a good time to start a
community design and development effort for USB cameras.

I believe we can (and should) provide an "official" version for
E-turtle, with experimental versions available for testing with
Diamondback. There is already a strong consensus that we need one.

As far as stacks are concerned, for E-turtle I hope to break up the
camera_drivers stack into several smaller, separately-versioned
stacks. Some, like camera1394, will probably use the new "unary" stack
packaging. There is no benefit to holding up a WGE100 bug fix (for
example) because camera1394 is not quite ready to release (or
vice-versa). Since these devices are typically not used on the same
robot, there is no reason to strictly synchronize their versions or
force users to download them all to get the one they need.

I believe we will want to continue grouping the various camera drivers
for documentation and interface coordination purposes. Exactly how
remains to be seen.

Comments and different ideas are wecome...
