Really slick Email, Calendar, RSS, IM and VOIP client done in Flash!

I just found out about this really slick client built in Flash that handles email, RSS and VOIP, adds a calendar and IM capabilities and wraps it into an interface similar to Outlook / XP. I haven’t seen the actual demo yet and i’m wondering if it’s build on top of Flex 2. Check out the screenshots (click for a bigger view):
