At breakfast this morning I was eating my bagel and perusing a MacMall catalog that came to me yesterday. While looking at the "completely wireless" option on the new iMac (bluetooth keyboard and mouse, Airport connection), I started imagining what our computer lab would look like if we were to populate it with this configuration. Then it occurred to me: What would happen if you had a roomful of bluetooth keyboards and mice? How does the computer "know" which mouse and keyboard is meant for it, and it alone? Or, can one control one's neighbor's computer from your mouse and keyboard? Anyone? Thanks. Charles Pearce (charlesp at ksu.edu)
