Sorry then Teralis, I know I sounded snippy and I meant it when I said it, but I apologize. I just figured it was more common sense than anything at the time. But honestly, I haven't a clue as to why they'd need it. Just an idea.
Thief/Bard Skill - Lock Door
*Crush Door *... That's a good idea, break a door down so you can't close someone in at all. Rather than you use a skill to trap someone, they use a skill to un-trap themselves, and maybe ambush people in the next room as a bonus, spraying them with splinters and stuff... That'd be a good way to open battle with some aggressive mobs out there. Of course, It would have to be unlocked before you could crush it.
Why would it have to be unlocked? Sounds like you are breaking the door itself.
there used to be a 'ram' command.
And there still is 
. Let's leave it at that.

Maybe 'no_pass' exits would be immune to rammage.
...Rammage. What an awesome word. 
Now you're talking! A door too thick for magical passage should not be rammable.
