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

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

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

Nikolaus
