A sound idea?

One of the projects that's been on "low simmer" for several years is a few Web terminals for an educational site. Since the applications will be running on a central computer, I may just connect a small amplifier and some bookshelf speakers to that (rather than buying cheap speakers and streaming audio to each terminal). The plan is for four terminals sitting next to each other. If I put one speaker at either end and adjust each terminal's software mixer balance, I should be able to make each terminal's sound "appear" where the terminal is.
