I joined Opera just before Unite was released. People told me that the idea was very old. They've been prototyping and re-working the product and were not 100% happy about it whet it was finally released. It seems to me that at that time it would be a great idea to wrap the API into some mix of standards that emerged over time (IndexDB, AppCache, etc.) That way writing Unite applications would attract web developers interested in HTML5. It didn't happen and most web developers saw some proprietary API for a browser with a small marketshare. No wonder it didn't took off. Something similar may appear on top of WebRTC like you suggested.
