Parleys.com, a prominent Java site developed by the team that organized Javapolis in Belgium, launched a new version of their website today, developed in Flex, along with an AIR application that they've developed that complements the site. Parleys.com originally launched a year ago, and hosts videos and slides from major Java conferences, including Javapolis, JavaZone and more. There's over 120 hours of video available on the site, synchronized with the slides from the presentation.

The Flex application is really well done - one of the top sites that I've seen. The user experience is really good - video quality is excellent, transitions are well done to let you know when things have changed, adding tags and comments is really easy. Full screen video is supported, and the quality of the video remains excellent.

The site also supports deep linking, so you can link directly to one of the talks deep inside the application. For example, here's a direct link to the talk about the new Parleys.com (you'll need to sign up for an account to view it - its well worth it).

The AIR application allows users to download the videos and watch them offline, and add comments and tags and then sync them to the server later.

Take a look at this site and AIR application - its a great example of using Flex and AIR to develop a truly compelling rich Internet application. And the AIR desktop support does a great job at complementing the online experience.
