The distraction rule from Bluff says that you may make a stealth check to hide if you distract your targets. This means that you use a standard action to distract, and then move to cover and hide behind it. The important thing is that your opponents don't know which cover-providing item he's hiding behind.
I'm not sure this is true. Once per encounter, Bluff allows you to use an opposed Bluff check to distract an enemy and make a Stealth check to hide.
Under Stealth, you may attempt to hide from a "Distracted Creature" even when you don't have cover and concealment.
Under the heading "Cover or Concealment": Without distraction, you must have cover or concealment to make a Stealth check. If a creature has unblocked line of sight to you (you lack cover/concealment) the creature automatically sees you.
I don't think that conditional cover scenarios like Allies will provide cover from an Enemy for purposes of making a Stealth check (since this type of cover only applies to range attacks, for example).
Combining "Distracted Creature" and "Cover or Concealment" together, this means you can Bluff without cover/concealment and if successful, immediately hide using a Stealth roll. However, it seems that you will need to move to cover/concealment or you're automatically seen, which really makes you wonder why you didn't just move to cover and then try to hide (and thus avoiding the Bluff check entirely).
Further confusing the issue is the fact that making a Stealth check is part of whatever action you're trying to perform stealthily. While sneaking, this would be a move action. Take this scenario, however:
A Rogue is fighting an Ogre. The Rogue takes his turn, attacks the Ogre (standard action), moves behind a corner (move action and achieves cover) then drinks a potion (minor action). The Rogue now wants to make a Stealth check to hide so he can have Combat Advantage on his next turn. What kind of action is this? A move action? IMO, it needs to have some kind of cost, just to prevent characters from making Stealth checks every round. Of course, by following the RAW, even if the Rogue makes his Stealth against the Ogre's passive perception, if the Ogre moves around the corner as well such that the Rogue no longer has cover, he will be seen.
Confused yet?
