Here's a movie I made in JO with cl_avidemo that demonstrates some destructable doors I made. You'll need the DivX (
http://www.divx.com) codec to view it. You also may want to do a "Save Target As..." instead of trying to stream it.

The first method I thought could be used for jammed doors. It could open partially, then close, requiring you to blast it open.
The second one is supposed to simulate how Qui-Gon melted through the blast doors in Episode I. With some nifty ICARUS scripting, I could make it so that when the door is activated, the player sticks his saber through it and you can watch it melt (like a cutscene but with no new camera views).
With some trickier scripting I might be able to allow the player to do it on his own.
