I tried including Logistics Pipes in my latest modpack and hit HUGE issues with it, on a variety of levels. I had a map corrupting trivial build for awhile. I shied away.
Consider using more of Immibis's mods, including
InfiniTubes. InfiniTubes has all the same properties of RP2 tubes without that lag. Unfortunately for 1.5.1 users, there is no mod that provides something as powerful and flexible as the sorting machine at this time for such a low cost and elegant UI. However, InfiniTubes can come very close.
These features are released and they are
incredibly good. Going from RedPower2 to MFR's RedNet stuff is a huge
upgrade in functionality and capability. The scope and capability of rednet far exceeds even the most sophisticated redpower2 stuff. So even if RP2 gets ported, consider learning and using these mods.
Just so you realize: it is possible to make fully functional computers by hand using MFR's rednet PRCs that are upgraded. They include many logic features you find in conventional digital logic chips including direct support for
seven segment displays, analog meters, and the new Thermal Expansion variable-light-output lamps!
RedPower 2 adds a few other things you might want to replace. For example, the humble canvas bag! We're using
Backpacks as a substitute. You may also want to use Gregtech's alloy furnace if you liked 1-step alloy-ification.
You may also be interested in the Universal Elecrticity pack if you'd like a more faithful representation of electricity like RP2 provided. Interestingly, UE's stuff plays very well with other power systems, and many mods in Ultimate can directly consume UE energy. Further, UE's Mekanism mod provides Energy Cubes, which are universal power acceptors (can accept any type of power but Factorization which the author claims to want to support) and outputs to whatever type the red side is connected to, using standard conversion ratios. UE also can be used to generate steam with many of its power systems, and claims to have more integration with this feature in the pipe. It's entirely possible to produce a huge sum of MJ from an Atomic Science nuclear reactor.
