I really like the idea that using the island's magnetic qualities to change where it appears on a compass is what constitutes "moving" it - that it's all relative. So instead of a course bearing of 305, it gets moved to 302, etc... Is that what you mean?
Still, that episode recently where Ben suddenly wakes up in the middle of a dessert wearing the Dharma Parka ("Dharka" someone called it
) seems to indicate that there's some-thing that can "teleport"...? Yes? No?
