Roy,
I have this camera and some features and findings:

* it has up to 480x320 resolution
* when starting the qpe-camera application, you get a direct preview on=20
the LCD
   My optical estimate is that this is done between 5 and 10 frames per=20
second
   I tried to move a pen in front of the lens to make an estimation by=20
stroboscopic effect, but it was not reliable yet without doing more=20
experimentation
* The camera is not mounted to /mnt/cf (like a memory CF card) - which=20
would not make much sense of course...
* I could not easily find out what the device name it is (it's not=20
/dev/camera ...)

So,
the camera seems capable to take a photo sequence (i.e. movie) by=20
software (as the preview does). The button on the camera just stores=20
the current image to memory.
Using the camera for video-conferencing would really be nice, as it is=20
easily installed or exchanged with other CF accessories and it is handy=20
for transportation. AFAIK there is no standard USB interface and they=20
may be a little clumsy.
The only drawback is that I can't use it at the same time with the WLAN=20
CF card - so there is no wireless online-connection while using the=20
camera!

If Sharp will bring out a Zaurus with both, integrated camera and=20
integrated WLAN, your app could become a killer. Unfortunately, there=20
are no indications at all that they will do.
