For you low-voltage guys: Is there ever a situation where you've pulled a new wire into a conduit with wire already installed? Is there any way to do this effectively?

All the time, and it's always a pain in the neck.
See if there's a wire that you can disconnect at one end and use that to pull in a string. Then, pull it, along with the new wire, back with the string.

Depends on circumstances.
Sometimes with short run little or no bends - and a raceway that is not too full you can push the added conductor in.
Sometimes you can pull out an existing conductor and pull in a replacement plus your added conductor.
Sometimes you are not pulling anything out unless you pull all conductors out.
Sometimes you are not pulling anything out period - or anything else in either.

Also, depending on the circumstances and the kind of wire, you may want to use a pulling lube. Not only makes the pull easier but it reduces the possibility of "burning" the existing cables or conductors.
