Could you have an argument 'discoved' in terms of ways, and if you have searched it or searched and used it a number of times that 'discovered' argument is considered true and thus a character would see a way?
It would also be good if hidden routes had a passive DC, so that if you had a high enough stat it would simply show up the hidden route. I always thought hidden ways could be abused meta wise if they are not gated by DC.
THis could also tie into the new 'point out' command I think was recently put in, where someone might be able to guide a lower level person through places and point them out.
