Skype video chat rooms
If you and another user are both on Skype, you can leave a video message rather than a voicemail.
Skype is always free to get, and free for calls between Skype users—you don't pay until you layer in extras, some of which are particularly powerful for business users.
With such ubiquity, Skype once accounted for close to 40 percent of all of the international telecommunications traffic on the internet, and that was just from Skype-to-Skype users.
And while Skype still dominates these "over-the-top" (OTT) communications services, competition is now fierce.
Or just disable the sound and screen on the "stealth" laptop so it doesn't give you away.
If you've got an external webcam, place it somewhere away from the laptop to still keep an eye on things—you'll just need a long USB cable.
Skype arrived in Europe in 2003, the brainchild of the guys who once ran file-sharing service Kazaa.
