It's rare, but it can happen. Anyone could be a target... although you're right, the mages will always be more vulnerable. Apparently rifters as well, with those shards of theirs... or so I've heard. [There is at least one pretty unsettling story about that rifter who got possessed about a year ago.]

It's good to know that you're prepared in case something happens. Messing with the Fade is all too dangerous of a prospect, after all... there's always potential for something to go wrong. [Are you gathering how much he distrusts all of this sort of thing? Because he sure does distrust it.]
