That stops all kinds of bizarre nonsense, such as ally-targeting powers being used to detect traitors, or a player who has an inkling that an ally is actually a traitor, trapping the DM as to whether he allows the targetting or not...
How is that a question?
Is the creature in question a willing recipient of your powers -in general-? Yes? Ally. No? Enemy.
His eventual plans to destroy you and betray you have nothing to do with that question. When he does betray you, then OBVIOUSLY he becomes your enemy.
The DM doesn't have to do any sort of trapping or being on the spot.
You're making it seem a lot more complicated than it really is.
And if he doesn't trust you, and you know it, then the DM is well within his rights to say 'Enemy' and your powers work on him in that way.
The 'are you willing for this power as a free action' is abusable as noted above. The rule's not supposed to be used to interchange your status on an action to action basis.
It's simple, and the DM has more than enough power to execute it properly.
