Two out of my three girls are walked on a harness and leash, and so far no door dashing (I'm knocking on wood now, before that one bites me! XD).
Alice has only rushed the door once, but it was around the time she was still exploring the house and getting used to the place...she ended up treeing herself due to a scarey little Yorkie dog, but we got her down with minimal effort.
We started walking her maybe a month after the treeing incident. She gets so excited to see her harness, it's absolutely adorable. She waits pretty well too.
Samantha loves her walks, and just takes her leisurely time about it. Even without her harness, she steps out on the front door mat with me (or on her own sometimes), and just looks around, takes a good smell, and comes back inside (I didn't get her to start doing this, she started it on her own...scared me half to death when she just waltzed outside on her own the first time!). It may be stupid to say, but I trust her to not leave. She's so attached to me, that I think door dashing will never cross her mind. (Then again, maybe I should knock on some more of that wood...).
Rochelle, as I've mentioned before, has no desire to ever go outside again. I have no idea why she's so frightened, but we've tried with the harness and just holding her close to us when we go outside, and she just freaks out...crying, struggling...as soon as her paws touch carpet though, she's a happy kitty again. I figure why mess with a good thing...she'll never be a door dasher, and thats one less thing to worry about when coming and going from the apartment.
