Orgoo allows you to integrate email and IM services into a single web-based dashboard. Additionally there are cool features such as the ability to create group chats and video chat all within the same space.
There are some issues to work out. Notably, in the comment thread on today's TechCrunch post, several expressed concern about providing passwords in order to incorporate accounts when there is no obvious security protection such as switching to a https URL. One of the co-founders jumped in to explain security features but it needs to be more transparent. Also, some services such as Yahoo! mail currently can only be incorporated if you are using the pay "plus" version and not the free version.
However, I am looking forward to trying the service out more as I really liked what I saw in the demonstration. The TechCrunch invites were snapped up in minutes but I have 6 to give. Please leave a comment and use a valid email address (which does not display, only I see will see it) and I'll send them out.
