For anyone that is as obsessed with LOST as I am, here's a theory i have:
We all know that mental time travel is possible, because of what Desmond has been going through. We also know that Ben gets off the island (because of his interactions with Sayid off the island). So my theory is that Ben is Ben's man on the boat.
I think that he gets captured in the future, and is able to jump through time and knows what's going on and is trying to make it all stop. He's trying to change the future, but he's probably not going to be able to.
I also think that Daniel Faraday is Jacob stuck in a time travel warp thing... he was exposed to radiation for a prolong period of time when doing those experiements with the rat.
