Yeah, I was looking at that. Not sure what you mean by "call the controller", though. That file isn't part of the API, right?
EDIT: Oh, you mean call it by CURL or what not ... yeah that would work

Actually, after tinkering a bit, that won't work, at least not as easily, because you run into vBulletin authentication issues with the cURL request
