Skype is an up-and-coming voice-over-Internet-protocol (VOIP) service from the makers of Kazaa. Using their experience in P2P networking, these kids have come up with software that has fantasic voice quality. The only problem with it at this point is that it’s computer-to-computer only, and doesn’t connect to landlines like some other services. It’s not fancy, and doesn’t support video at this point, but it’s free and works around the globe. And supposedly it cuts though firewalls like butter, making it great for calls from work.
One more thing: It’s ad-free. For anyone familiar with Kazaa, that’s good news.
