Anyone got anything (or know of) to activate the lock in WinXP (basically, the Win button + L) by voice activation. I have friends that seem to want to mess with my comp when I am doing something, and it'd be really cool to just say something like "computer lock" outloud and have the system lock it self. I don't care about unlocking it with voice recognition, but if anything has that too that'd be awesome.
 
Thanks!
