That list might have brought a tear to the eye of some reading this: Chrome is supported only on Windows initially, which means that it’s not yet the web-based Skype solution Chromebook owners have been waiting for. It should sync up your various conversations and message status, and let you get chatting quickly, and it also lets you call friends with a single button press once you’ve installed that plug-in, on Chrome for Windows, IE, Firefox or Safari. The Skype web app is designed to eventually work without any plug-ins, which again goes to the point of it being usable without install permissions, but initially it will require you to install a single small plug-in to get voice and video calls, while Skype works with Internet Explorer to bring Real-Time Communications (RTC) standards to that browser. The Skype web client also allows anyone to sign in and use it their account when they’re on an unfamiliar or public computer, without having to be able to install native apps. Skype has brought its instant messaging, voice and video chat service to the browser with a new beta available now. That includes support for third-party audio conferencing providers, Skype for Business Online Cloud Connector Edition, hybrid voice configurations, and Skype Meeting Broadcast.Update: Good news! Skype says that Chrome on Chromebooks and non-Windows platforms can use Skype for Web for instant messaging, but not yet for voice and video because the plugin hasn’t been configured for them yet. Microsoft also warned that services that integrate with Skype for Business Online will not be supported beyond July 31.
