The PAR driver is not a network driver. That means only one process at a time can read or write frames from/to it. You cannot have two (or more) machines asking it for different frames at the same time. When a frame is requested from the PAR, it is converted to Targa first and then sent to the calling application at the application's own pace. If a second process comes along and requests a new frame, the driver doesn't know what to do with it as it only has one buffer to read Targa frames (this buffer is 1080 kbytes long).
