Skype is coming to the Web with in-browser instant messaging, voice, and video chat.
To start off, it's going to need a plugin to enable the voice and video portions, and it will support Internet Explorer 10 or newer, the latest versions of Firefox and Chrome, and on OS X, Safari 6 or newer. Rollout has started on an invitational basis.
That browser plugin should be temporary, however, as eventually it will use the open Web standards even for these parts. But this is more complex than it sounds, thanks to disagreements about the best way to support audio and video streaming on the Web.
