(Provided those things are computationally expensive to recalculate, and the memory cost of caching them is less than the time cost of recalculating them each time.)
They should be much more efficient now (this reduced the tick time of the CI Chamber by 3-4x in my testing), due to being able to just use the HashMap's get() instead of being limited to iterating through entries. NEI integration code now a lot more readable and type-safe as well.
I went for what seemed like a good level of organisation:
Java

Mekanism

FML

Netty
LWJGL

Static Imports.
Also special facing support. Salination Plants now fully connected - the Controller texture could do with some cleaning up to improve the connected look.
I've made modifications to the original system to allow multi-meta CTM, such as between Dynamic Tanks and Dynamic Valves. This also allows texturing with effectively 5 textures, as opposed to the 47 needed previously
