The infamous brains behind MegaUpload, Kim Dotcom, has just launched the beta version of his latest product: a browser-based encrypted video calling and file-sharing service he hopes will take on the Microsoft-owned Skype.
Called MegaChat, the service uses what is called User Controlled Encryption (UCE), meaning that you get a decryption key provided, and are then free to send it to people so that they you can trade files with them. Like the Web-based MegaUpload, no software installation is required, although there are Chrome and Firefox extensions which aid with improved performance and security.
