mDiyo was ranting about needing cool teleporters in MC that "just worked" and I got an idea for a GUILess feature of the Wraith Node, when you run into one, it scans in the direction opposite the sideHit for another node, in a cone shape, and portals you "after" it, basically allowing you to set up relays using Wraith Nodes. If you jump on it, it scans down, bump it from below, it scans up, etc etc. Planning on using entity collide events and some world save data to store placement info to assist the algorithm with location, and writing a custom method to figure out whether two nodes exist in eachother's cones.

For the time being I was thinking 100-400 meters is as much as I'm willing to allow them to move, travel wise, which seems like it isn't much, but the idea is that you can set them up in relays and turn a 500-2000 meter walk into about 5 steps. Also making them directional allows you to set up a lattice, in a sense, letting you freely "jolt" across large distances wherever you've set up nodes.

Since the nodes themselves are capable of being marked as a recall point with the ender staff, it would just be one more neat thing they can do. I'm thinking the function would be free, since the "cost" of using them is having the materials to scatter them around your world.
