Anybody using Gmail? How about Google Talk?
If so, 2Entwine has created a truely awsome Flash App called Gtalkr!! Right now it is Beta 2.0.0.67, but in my opinion a very promising RIA (Rich Internet Application).

• Google Talk contact information
• Contact presence changes
• Gtalkr Notifier integration
• Drag and drop support

It lists friends, your Gmail Account, a Flickr slideshow, a YouTube component, and much more…
Still not enough? Well Gtalkr also has a blog, Everything Gtalkr that will keep you up to date!!
Still want more? Well it even supports extensions!! A combination of XML and Flash…”you’ll need to create the Flash file that Gtalkr will load.”
I see a lot of potential in this application and fresh view on customization that other portal technologies lack….
