No, I still haven't tried Ekiga (I'm going to test it when I have the
time), but I still need to have the webcam working with all these other
applications.

Do you mean that all these applications use the v4l or v4l2 interface
incorrectly?

Do you have plans to have v4l1 compatibility in the driver?

I still don't know what ioctls should be in a v4l2 driver with v4l1
compatibility using v4l_compat_translate_ioctl()
Do you know where I can find that list?

Do you know of a good webcam USB driver that has good v4l1 compatibility
using v4l_compat_translate_ioctl() ?
I saw http://www.saillard.org/linux/pwc/ but it has both v4l1 and v4l2
APIs.
