Steve's carts perform many of the duties that forestry did. Beyond that, Forestry was redundant which you could pretty much do with items from BC and IC2. Which just required more manual work which is a fun aspect of Tekkit.
With the demise of Railcraft now, I was really looking forward to using the huge iron tanks and water towers, and maybe someone can add something similar so we can use them to store our lovely fluids and generate water without destroying the map, or cheating with the water reforming mechanic ie: [water][air][water] -> [water][water][water].
The whole idea of liscences are stupid. The software in the mods are freeware and have an unconditional acceptance of use and distribution, so long the original creator and maintaining team are credited. If malicious code was added to a mod (malware, which violates Computer Abuse Act 1990) by disrupting a program intentionally, should have their modding rights severely penalized. Children play this game, and adding malicious coding can lead to all sorts of trouble which can result in a serious investigation, and ramifications for the modder, the game developers and the future of minecraft and relating projects.
