Opera Unite is a collaborative technology that allows you to share, connect and collaborate directly between computers across the Web, without going through a central, third-party server.
How Opera Unite is different to traditional data sharing
With more traditional content sharing, you have to upload the content you want to share, and this is then stored on a central, third-party server, out of your control. Your friends access this stored content from the third-party server.
With Opera Unite, your friends view the content that is sitting on your computer.
