Teleport pipes from Additional Pipes for BuildCraft can now be crafted. There is now a mining world; however, it is simply my old adventure world code enabled. To enter the adventure world, stand in a nether portal while holding an enderpearl. To get back, use your brain! Please aware that teleporting through a mining world portal may temporarily freeze the server, so maybe warn others before doing so. Apiarist's Pipe/Backpack/Chest are not going to be fixed as they are not supported on SMP.
Will teleporters be made craftable again or do they have just as much chance as that as the forestry stuff does?
