You'd need to change the kernel driver to not grab directly into mmap()'ed buffers, but in an ever-lasting buffer queue and memcpy()s these buffers to the mmap()'ed buffers if userspace requests a frame. Then, you can give a frame to more than one application. However, using memcpy() in the kernel is ugly, especially on these high-data-load tasks like video capturing. Besides that, you're wasting precious memory for the driver's buffer queue. So it's not a very nice solution. But you could always give it a try. ;-).
