Someone sitting way to one side, for example, would not hear a centralized image - they would hear dialogue come from the closer speaker and think "WTF?".

In if this is the case then I think it's fair to say that the central channel is unnecessary if the viewers sit between the two speakers and the speakers are properly positioned. In that case, the viewer will hear a pinpoint image as good as, or better, than can be created by the center channel. For a 5.1 signal, the center channel info can just be fed through the L and R front speakers.
Indeed. Out of place and not tuned can be hazardous to sound imagind and reflection. But then that depends on the speaker type as well. The center channel is very neccesary as it is the focal point of all direct audio. Try this. Try hooking all your speakers up including the center, play a movie, listen for a bit and unplug the center. See what happens.
