Installing New Services
At this point, click Add on the main Opera Unite menu. It opens a web page in the browser. Click Install on a service you want to try. It will download the widget and open a window for you to enter the directory path you want the service to access. Be sure to click Advanced on that window and disable Make Service Visible on Opera Unite Websites. The company says that any service widgets made available from them will be verified as safe. Presumably, third-party developers will make them available from their own sites; it's your decision what to do about these.
Make sure the widget admin screen for any content you want to serve securely has public/password options; the Stream media (video streamer) service did not have one at the time this was written.
