We first reported on Opera Unite when version 10 of the Opera web browser was released in September.
At the time, Unite was not yet built into the browser, but is now with this latest release.
According to Opera:
Opera Unite is a new technology platform allowing you to share content directly with friends without having to upload anything to a Web site. You can stream music, show photo galleries, share files and folders or even host your own Web pages directly from your browser.
It will be interesting to see if the other major browser makers start to employ similar ideas into their products.
