A small point. Most shooting techniques I've seen involve a ball that is headed upwards well past the lexan barrier. Thus, I'd think you could block shots right at the lexan barrier. however, you'd have to do so with blocking your opponents vision, as that's illegal.

EDIT: I think it's physically impossible, or atleast very very difficult to shoot a ball at the stationary goal and have it arcing down at the barrier, and STILL have a reasonable chance of going in. That being the key point. Goaltending can't be called on balls that patently aren't going into the goal. Else, you could just hit robots with balls anywhere on the field to score points.
