Windows Live Messenger with VoIP
V-man writes "Microsoft has just launched Windows Live Messenger with free PC-to-PC phone calls and PC-to-phone calling as a pay service provided by Verizon Web Calling. Of course, most people doing PC-to-PC and PC-to-phone calling are probably using Firefox...too bad the Launch Page isn't Mozilla friendly."
The nice thing about dealing with verizon is that the U.S. government will archive all of your conversations for free! Of course, you may not be able to access them, but it's nice to know there are backups out there somewhere.
