Move the Island?

I don't usually crow about making good ejucated guesses where this
show is concerned, but it is kinda nice to seemingly get it right now
and again...

In this case, it was the mysterious bit of dialogue between Ben and
Widmore about Widmore "never finding the island" even though we know
he has a darned good idea where it currently exists in Craphole Island
time....

RWG (so it seems like Locke and company do somehow end up being able
to "move it" in a way that makes it much more difficult to find)
