adjustable distributors?

What about the MSD E-Core/ E-fire whatever that really nice distributor that they make and it makes me hate MSD for not making one in slant six format.

You know, the one that has the control module and coil built in like HEI dials you can turn with a flathead screwdriver to adjust initial timing as well as the rev limiter? If im not mistaken you can even plug in a laptop and change your timing curve as well.
