Here are some observations:
- The logs always come from the same IP running the Opera Browser
- Images don't show up in the apache logs since the Opera Unite WebProxy chooses to serve those directly
- Opera Unite seems to startup automatically if the browser is allowed to save the password
- Opera Unite doesn't seem to work with The Onion Router
- There doesn't seem to be great community support on the Opera Unite forums
- You can't place robots.txt or sitemap.xml in the domain root since the Opera Unite Reverse proxy manages that path
