The Opera Unite service, which is similar to a http service, actually works, but barely. In 95% of a browser's request to open a user's web site:
http://mypc.myusername.operaunite.co...erver/content/
the browser says:
503 Service Unavailable
No server is available to handle this request.
Connection Interrupted
In 8% of attempts, the browser says:
The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection. Please try again.
In 1% of attempts, the browser shows the Opera Unite's member's web page, often incomplete.
And in 0.5% of attempts, the browser actually delivers, say, a large file.
There are so many betas in the world... Maybe the authors have seen too many rehearsals of "Madama Butterfly." (Seeing a rehearsal is far more easier that seeing a real evening performance.)
