Off-topic but related to gathering nodes, they can be gathering from a range longer than you'd expect (much longer than interacting with quest objects). And they aren't effected by line of site. So, for example, I've nabbed slicing terminals while standing under the bridge it's on, or behind a tent when the tent occupied by mobs I didn't feel like fighting (that one was tricky, had to zoom out and turn the camera at the right angle to see inside the tent).
