Having been in the VoIP market for years, I can't believe that eBAY paid 2.6 BILLION (with a big B) for something as crazy as Skype! I use a VoIP-SIP based service called GIZMO (
www.gizmoproject.com). They have much better software, even allowing you to be your own NSA and record your phone calls; voice mail, and even free incoming calls from the PSTN (if your caller is willing to use a PSTN call that may be toll to them). They have 800, and 1 cent/min calls to US/Canada. The quality is excellent IF you have a solid cable or DSL connection. Not even bad with satellite except for the 480 msec delay due to uisng GEOS sats.
Anyway, just thought that people might want to try something that shows how anything on the Internet can be duplicated, improved, and enhanced without spending 2.6Billion. We will be studying eBay's snafu for years in our MBA programs. ;-)
