I'm not sure what the capabilities of video4linux are, which devices it 
supports or how its API works.  I know it supports at least some USB 
webcams.

The idea is to use the video4linux interface to implement the VFW API in 
Wine. The way I usually go about this kind of thing is to write a 
program or find a simple program (hopefully one with source code) that 
can grab a picture from a WebCam on Linux.  Then run it in Wine, and see 
which error messages come out... then you'll have a starting point. 
Looks like there's souce for a simple program like that here:

and documentation for VFW here:
