  Well, looking at the code currently in CVS, the problem really seems to be 
that the check_inv bails out if the triggerer is not a player.

  However, I'm not sure how an inventory checker can be used to control the 
trail of ants - the inventory checker doesn't limit where they can go, other 
than being connected to some other object (say a gate or whatever) which limits 
where they go.

  I wouldn't really see why the order we are checking would make any difference. 
  And looking at the code right now, it seems to check the player object before 
checking for matching objects in the inventory.

  so I'm not really sure what is trying to get fixed here/what is currently 
broken, aside from perhaps the fact that the player check is still there.
