And this is no good. Now that Microsoft owns Skype and integrates it into the next versions of Windows, other VOIP projects are doomed to become meaningless.Now that Microsoft owns Skype, the Free Software Foundation is likely to hate Skype even more.
You may tell me "it is the same thing people said about every browser other than explorer 10 years ago, but then Firefox came and things changed". No, it isn't the same. Not at all. The browser war was possible (itself) because HTML is an open standard, and any browser you mind to write would be capable to play it. But Skype protocol is tight closed, overpatented and overcopyrighted, and not compatible with other protocols. If you can't write a Skype client on your own, there's no chance you can IP-phone to the majority of Ip voice users.
