Well, there's lots of ways to do that, actually. They could do it like it was done in City of Heroes, where when you sneak or activate a stealth power or whatever, you turn invisible to non-allied players. Players with a good enough perception would be able to see you, but those without would not, and you could backstab/pickpocket them. I doubt the backstab would be a one-hit KO like it can be in previous TES games, but it would probably do a lot of damage.

Or maybe the Thieves Guild and Dark Brotherhood quests would be PvE only, so you don't have to worry about sneaking up on other players.
