The blogosphere is all abuzz over Google's launch of Lively, an in browser virtual world, similar to Second Life.

However, the bigger news for RIA developers, and especially Flex developers, is the technology that they used to build it. From this Flickr screenshot, it appears as though Google is using Flex to develop the UI for Lively. This assumption is also supported by the minimum system requirements, which list Flash [Player] 9 or higher. (Flex applications can only run in Flash Player 9 or higher because of the new VM requirements.)

Since Lively only runs on Windows machines (and not in VMWare) I can't personally test this out - can anyone verify the Flickr screenshot?
