BLACK SWAN'S Mark Heyman shopping thriller XOXO

Black Swan writer, Mark Heyman, is currently shopping a new script for a thriller titled XOXO. The LA Times repots that Heyman is currently shopping the script around Hollywood, which will be produced by Darren Aronofsky. 

The story is said to be "Fatal Attraction but with Facebook". It focuses on "a twentysomething man who meets a female contemporary on Facebook and begins a digital relationship with her, only to find the object of his affections take the relationship to an obsessed and stalker-y place." The project will use streaming video and other social media platforms in addition to Facebook to tell the story. 

I am interested in seeing how this story develops. When I saw the trailer for Catfish I had hoped that it would be something much darker than it ended up being. This has the potential to be very cool, what are your thoughts?
