MMF Demo: Wixi

This is the 3rd time I've seen Wixi -- first at TC 40 this fall, 2nd on the panel I hosted yesterday on social media, now he public demo this morning.  I still don't get it.

Wixi is designed to enable group sharing of media.  People create their own "wixi" page by dragging and dropping files onto a windows vista-like web page, and then their friends/colleagues in their circle can basically access their media online.

My take is that it's sort of like a digital locker with some social elements.  I guess it makes some sense for folks who want to have anywhere access to their media from multiple devices and locations, and to then be able to share that with their friends.  But, can't you just share your files with your friends on Facebook?

Concerns are obvious:  facilitates music / video stealing.  Also, does this just become an easier way for like people to share porn? 

I also don't understand how they are going to make money from this.  Not sure why anyone would pay for their premium offering which just offers more online storage.
