As I said, I'm not sure about that. But coordinated insertion into separate machines is something AE cannot do at all, at least alone. LP might also be better feeding the induction smelter by use of sattelite pipes, but I never tested that. In my current world I'm way beyond needing to conserve supplies so rather than trying to fiddle with LP I rather build more machines =)
I also no longer have the magma crucible/liquid transposer setup running, TE bees/mystcraft + individual transposers ftw
(also I'm mostly using Ender IO now, so my need for liquid redstone is rather low)
What I probably will use LP for (if I really will bother with it) is efficiently feeding MFR biofuel generators, that's something AE can't do at all, at least not without a lot of shenannigans.
