I just had a very pleasant encounter with webcams on linux - I tried to use
gnomemeeting from a knoppix distribution, and while gnomeeting itself made
some trouble, the camera was detected correctly and e.g. gqcam can be used
to get images.
I even wrote a simple python-script to search for attached video-devices
using some translated C-code with ioctl-calls. Worked like a charm.
For the QuickCam I had to patch and recompile the kernel, as the module is
not in the tree, but then it worked as expected.
