A pass route in which the receiver heads downfield, then quickly turns back toward the line of scrimmage.
I cannot speak to those specific rules of football, but in general, lineman are allowed to be downfield on any pass where the ball is caught BEHIND the line of scrimmage.
No. It is illegal for an eligable man to block a defender past the line off scrimmage if the ball is in the air.
Downfield is "in or into the part of the field toward which the offensive team is headed," according to the Merriam-Webster dictionary (1), and is consistent with the use of "downfield" in the football penalty, Ineligible Receiver Downfield. Unfortunately, as of this date (10-23-11), Merriam-Webster has the same definition for upfield as it does for downfield (2)!

That depends. If the foul occurred behind the line of scrimmage, then the stats are nullified. However, if the foul occurred downfield, the players will still get credit for any carries/yardage up to the point where the foul occurred.
Defense Pass Interference (DPI) has not changed recently in the NCAA rules. It has "always" been a spot of the foul penalty, but not to exceed 15 yards from the line of scrimmage. So, if the infraction occurs 8 yards downfield it is an 8 yard penalty. If it occurs 52 yards downfield it is a 15 yard penalty.
Runs through the line of scrimmage (line of the players) or gets the football and runs outside the line of scrimmage.

In the NFL, there is no such thing as pass interference (PI) on forward passes that do not go past the line scrimmage but I recently watched a college football game in which a PI was called on a forward that never reached the line of scrimmage even though I always believed that there is no such thing as PI if such pass was in the backfield (behind the line of scrimmage). So I am not clear on the rule concerning passes that do not cross the line of scrimmage, in college football.
