Aikoa project is well under way. The service will enter beta phase in Winter 2008/2009.
No, I do not think they'll be in beta this winter.
I change my position. At first I thought this was prosper, developing a product for Finland. Now I believe this is somebody else entirely, and they've just been stupid and copied a lot of text from Prosper.com, including the names of the Prosper principals.
Here's why I've concluded this: If this were Prosper, they would use the software they have. They'd just change the skin and some of the words, and the language. These aikoa.fi people appear to be developing new code.
