A wireless access point, like the AirPort Base Station, the AirPort Extreme Base Station, or any other brand access point, can usually handle multiple clients. I seem to remember that the original (Graphite) ABS was limited to only 10 clients, but some access points can support as many as 250+ clients. Even the Software Base Station can handle multiple laptops. The only limitation you need to worry about in most cases is range. Managing the clients is automatic, once everything is set up.
