Mark is already doing the best possible work on the kernel.

In fact, many of the features Mark is adding to the kernel would work better is they were put into the player software. Mark is doing a lot of "tricks" that allow the kernel to handle special features that you'd normally do inside a piece of application software.

I would predict that if we could get the player software code open-sourced, then Mark would move a lot of his kernel features back into the player software where they belong.
