You know Wake-on-LAN? Great tool for IT, but not for the general public. Enter Remote Wake from Intel.
This feature takes WOL and ups the ante by allowing VoIP and media server programs to activate a sleeping computer. So if you have a Skype call from your buddy in Amsterdam while you and your computer is sleeping, the ‘puter will turn on and then wake you from your own slumber. Also, Orb and Cyberlink have shown interest so remote video watching wouldn’t require a user to keep the computer on when traveling. Price: don’t know yet. Availability: next month.
