Lost season 6: The touch of Jacob-What does it mean?

More possible clues from ABC's recap of the season 5 finale? Reading through it, I see that there are several references to Jacob touching, not touching, key characters. This seems to signify something important--something we can speculate on endlessly until season 6 finally arrives!

Check out these excerpts :

...a small-town general store: Young Kate and Young Tom plot their crime: they want to steal a New Kids On the Block lunchbox. Young Kate snatches it and hides it in her backpack, but on the way out they're caught. The owner threatens to call the cops, but a man steps forward and offers to pay for it. The man is Jacob. Young Kate tells him thanks, and Jacob asks if she's going to steal anymore. She shakes her head no, and Jacob smiles. He reaches out and taps her on the tip of her nose. "Be good, Katie," Jacob says and leaves.

...a funeral outside a Southern church: Young Sawyer watches as they load his mom and father's caskets into hearses. Afterwards, Young Sawyer is trying to write a letter but his pen won't work. Jacob walks up and asks if he needs a pen. He hands one, and as Young Sawyer takes it, their fingers touch briefly.

...Los Angeles and an intersection at Santa Monica Boulevard: Sayid and Nadia wait for the light to cross as a man standing next to them looks at a map. The man is Jacob. Nadia steps into the crosswalk as Jacob asks Sayid for help. Sayid looks at the map and asks where he wants to go -- as VRRRM -- KA-BAM! An SUV plows into Nadia. Fast. Shocking. Brutal. And during the moment of impact, Jacob reaches over... but does he touch Sayid's shoulder?

...Jacob reading a book on a bench: It's a quiet, peaceful moment -- and then we hear the sound of glass shattering. Behind Jacob we see a man fall out of an apartment window and drop to the ground! THUD! A woman screams and people yell out to call 911. Jacob stands and is the first to walk over to the man -- who we now see is John Locke. Jacob reaches down and touches him, and Locke sucks in a breath, in shock. Jacob tells Locke everything will be all right and that he's sorry this happened to him.

...Sun and Jin's wedding as they exchange their vows and Sun slips Jin's ring on his finger. Neither of them have ever been so happy, and the guests applaud. Afterwards, receiving their guests in line, Jacob approaches them and puts his hands on their shoulders as he speaks to them in flawless Korean. He offers them his blessing, and wishes them a long and happy life together.

...Jack buys a candy bar from a vending machine but the candy bar is stuck. He hits the machine a few times but it doesn't budge. Christian comes in and tells Jack that the girl is in recovery and there's no paralysis. Jack says Christian embarrassed him in front of the entire team by giving him a time out. Jack knows his father doesn't believe in him, but he needs his team to. Christian asks if Jack's sure Christian is the one who doesn't believe in him and then leaves. At the vending machine, a man makes his selection and Jack's candy bar drops. He holds it out to Jack and asks if it's his. The man is Jacob. Jack says yeah, the machine jammed. Jacob says guess it just needed a push. And as Jack takes the candy bar, their fingers touch slightly.

...the Los Angeles County prison as Hurley is released: He gets into a waiting cab only to discover someone else is already there sitting next to a guitar case. It's Jacob. Hurley starts to get out, but Jacob tells him they can share the cab. As the cab drives off, Jacob tells Hurley he was waiting for him. Hurley asks if Jacob is dead, and Jacob says no. Jacob wants to know why Hurley won't go back to the island, and Hurley says that he's cursed. That's why the plane crashed, and why his friends died. Now they visit him, and he can't stop it. Jacob asks what if Hurley isn't cursed but blessed? He gets to talk to the people he lost. Isn't that a wonderful thing? Hurley says sure, except for the part where he's crazy. Jacob tells Hurley he isn't crazy. Jacob puts his hand gently on Hurley's knee and gives him the flight information for Ajira flight 316 at L.A.X., and then waves the cabbie over.
