Since we are running natively within the browser and do not expose a
hardware API directly (as WebGL would have done without the extra
security layer they had to add on top of OpenGL), we should be in a much
better situation.

XFlow is pretty much the same. Instead of simply exposing
CUDA/OpenCL/whatever we have put a higher level declarative wrapper
around it that on the one hand allows Web developer to more easily deal
with predefined functionality they can just use but on the other hand
allows us to have more control on security aspects. Since all the data
comes in through well structured vertex arrays, the interface is well
defined and well defensible.

Having said this, I should add that we have not done a careful security
analysis yet.
