As I understand it, the new Sekonic L-478DR light meter would permit me to control the power of my remote speedlights from the meter. Does this mean that I would not have a need for the Pocket Wizard AC-3?
Another question I have is whether I'm required to mount an SB800, 900 or 910 on the camera in order to use the Sekonic to control the remote flashes in TTL mode.
So this brings up something I was wondering about. If I use a 478 to adjust the levels of my lights and I also have an ac3 and also make an adjustment from there, are the adjustments cumulative? Or does one over ride the adjustment of the other?

According to the instructional videos I've been watching, you use the Sekonic to set your flash levels and you must dial in the same levels on the AC-3, but it's the Sekonic which does the controlling. There has to be one "boss" so it is not cumulative.
Here's the scoop. In the flash setting screen of the Pocket Wizard software you set your MiniTTL or FlexTTL to "trigger only". When you meter you adjust the flash groups to your desired levels with the meter. When you trip the shutter, the levels are not altered. You do not need an AC3.
You do need CTL for the flash meter to communicate with the FlexTTL receiver to set the levels. Therefore you need a CTL transmitter to trigger, but trigger only.
I have custom setting one set to CTL with iTTL triggering and custom setting two set to trigger only for meter use.
