King Lemming, TE is a brilliant and essential mod. I make extensive use of it. TE machines come in VERY handy with Applied Energistics ME systems, and where would we all be without tesseracts, conduits, liquiducts, energy cells, and igneous extruders? The best GUI in the business. I love TE.
Now, you are likely working on new code presently, so I won't make the same suggestion that you have surely heard a thousand times already... *cough* tier two/three machines *cough* (LOL, sorry, couldn't resist). An "advanced machines addon" type of thing for TE machines.
