Earlier this week Skype (Microsoft) killed several Linux and OSX versions without warning. Users of Skype on some platforms can no longer connect to Skype servers. Feel free to express an opinion on that.
But my question is: If you want an open source & open protocol solution for Linux, OSX and Windows - what do you do?
Ekiga has windows binaries but nothing for OSX. That could be paired with OSX xmeeting but xmeeting does not look regularly maintained.
