Mechanically it's more like super insight than mind control, but fair enough.
When our people have a better understanding of how magic 'n shit works here, I'll re-evaluate the option. Until then, I don't want a particularly canny fellow with mage's eyes (directly or indirectly) seeing a minor drain in mana/magic/essence and suddenly watch our character's behavior change.
That's a potential problem with the CoST charm, but it's much easier to get away with it when you can just talk to joe schmoe the desk clerk or pick up a random book from the shelves and activate it there.
EDIT:
Fair point. Gimme a sec
