Variation on a theme, but still a fun one. EQ2 only checks whether a node is 'in range' when you first start to harvest. So, let's say you're in a heavily farmed spot like Fear-Tainted Isle. You have one node in front of you, the other guy has one. (Or the node is guarded by agro mobs.)
Start harvesting the node you're on.
Before the timer runs out, target the distant node.
When the timer runs out, you've harvested the other node.
Rinse and repeat.
