"Hello, I got an idea recently - 
motion blur inside of cycles is quite heavy on performance, while the vector
blur compositing node suffers aliasing problems - 
is it possible to actually do vector blur at the time of writing the sample 
into the image?
This way, a fake but well antialiased and potentially fast motion blur could
be achieved?
