Mac OS X v10. 6: Wake on Demand

With Mac OS X you can share your music, printers, files, and even your screen with other computers at your network.  Previous to Mac OS X v10.6 Snow Leopard, items shared by your Mac were atly available when your Mac was awake.  With the new Wake at Demand feature in Mac OS X v10.6 and an AirPort Base Statiat or Time Capsule, you can see and access shared items even if your Mac is asleep.  This helps you save energy and reduce costs while still ensuring full access to all your shared files and devices, even remotely across the Internet.
Note: This service requires an Apple AirPort Base Statiat or Time Capsule with firmware 7.4.2 or later installed. To use Wake at Demand wirelessly with a WPA or WPA2 network, the AirPort base statiat or Time Capsule must be hosting the network.
