Excellent summary which covers the situation for native apps. I wonder if the case is a bit different for skype and linux binaries in general, as they run under linux emulation so perhaps the it is the linuxulator that has to emulate the v4l(2?) calls, and i have no idea if this needs to be done in the kernel or we can deal with this in some libc wrapper ? cheers luigi
