Since creating DCPs takes so much time, I was really

The graphs I saw were difficult to compare to modern CPUs/GPUs.
Will it be hard to implement the usage of both the CPU and the GPU for encoding? Am I
silly for hoping this might be good value, or is it better/cheaper to get more
CPUs?
It would be nice, and there does seem to be some evidence to suggest that
a speed-up is possible. If openjpeg did it, DVD-o-matic could use it very
easily. Sadly I don't really have the time to get into it myself just
now.
As it stands, more CPU wins!
