Microsoft has recently announced its plan to allow users to make video and voice Skype calls from within a web browser. This means that you don’t need to download or install Skype software. All you need is extension/plugin for your favorite browser. Microsoft plans to do away with the download of extension/plugin later once WebRTC is more widely implemented. It is going to be especially useful if you are in an internet cafe in a foreign country with restriction to downloading any software.
Currently the service is in beta version and available to only selected users.
