Yes, that is Second Life running on an iPhone... kind of. According to Tech Digest, it's really a very different kind of proof of concept:
"In a layman's nutshell, all the processing is being done NOT on the iPhone, on a central server. All that's being streamed to the iPhone is the visuals - essentially, a video feed of the Second Life environment. Then, when you tap the on-screen buttons to move, or type in a message, that's sent back up to the server for processing."Personally, I'd settle for being able to IM from my phone to avatars in Second Life, and hopefully we won't have to wait too long for that...
