If they play super deep on the pitch, then it's possible the ball could be hit 150 feet from home and still be an infield fly. It is not relevant whether the ball is caught or not.

I'd give a rule cite, but my ASA book is out of date. It's the basic IFF rule, though. (Edit: Rule citation: Rule 1; Definitions for Infielder and Infield Fly)

I have an infield fly. The batter is out if the ball is fair, and the runners are free to advance with liability to be put out. They are not forced.

You can't make a ball hit to the warning track an infield fly by positioning your infielders against the wall. The definition for an infielder is someone who covers the ground normally covered by infielders.
