So are you saying the R930II converts Pentax P-TTL to Nikon i-TTL and thus gives you P-TTL with a flash that is triggered by the X1N, X32-N, etc.?
Or are you doing your usual "
fair comparisons" again?

Every radio trigger solution requires a receiver for each flash. Some speedlights have radio receivers built-in, but there is always a receiver. As paulster pointed out, the Acon and Cactus triggers do not differ in their support of foreign triggers on their hot-shoe in principle, so you can have the "no receiver on every foot" solution with the Cactus as well. The problem with this particular set up, AFAIC, is that you have a stack of triggers on the camera. I prefer a smaller and lighter arrangement with quick and safe access to the trigger controls for de-/activating speedlights, adjusting their power individually or simultaneously, etc.
