Yeah, it's a little tricky.blargney the second said:I see what you mean. The part I neglected to mention was that the description of swift actions references free actions, which in turn "rarely incur attacks of opportunity". It's not really explicit one way or the other.

In the Magic Item Compendium, swift-activation items incur AoOs if it's a 'manipulation' action, but not if it's 'command' or 'mental'.
Personally, I'd go with treating a spell-like ability as a spell unless otherwise indicated, in which case they don't get an AoO. But I can't claim that there's firm support for that interpretation in the rules.
