If you didn't catch the to-do recently, Viber founder/CEO Talmon Marco was nearly arrested for using his own VoIP service on a Delta Airlines flight.

Well, now Virgin Airlines will begin allowing in-flight calls over the Atlantic, and not just with VoIP. Passengers already use wi-fi for Skype, according to BBC News.

Skype, the ever-popular VoIP service, has a flaw that allows malicious users to track other Skype users' location and p2p sharing activity. Apparently, you can obtain another user's IP address during a call, or even through a brief call without an answer.

"Even when a user blocks callers or connects from behind a Network Address Translation (NAT) -- a common type of firewall -- it does not prevent the privacy risk," according to a release from NYU-Poly.
