Great! The fact that this is private is a huge +1 for me. Looking forward to trying it out! I saw one of your comments on the data being available at ~/Library/Application\ Support/Qbserve/ it would be good if the schema was documented on the site, maybe in a developers section?
No. They stated that Home Theater is still available and open sourced, although they are not working on further development and are focusing on the new Plex Media Player instead.
