Hello I absolutely aggree that VfW is an obsolete standard. I only mentioned it because it was the standard when I developed the video module for iPath. But the principle is the same no matter what kind of drivers for video is used.
The idea is that of a client application that can login to care2x and then identify a patient and then on the press of a button grab an image from the video stream and send it to the specified patient folder. For those interested, i could set up a simple demo of the concept with our iPath server at Uni Basel. To test the current solution, you will need a VfW video source and an internet connection (port 80 is sufficient). If there is interest, I'll post a short description soon.
