They seem to be oversimplifying "US Patent 7406501 System and method for instant messaging using an e-mail protocol". It's not "just" instant messaging: the actual useful bit is the "reply to email to send instant message internally" functionality that FB notification emails have.
Still not patent-worthy, of course, since any coder will instantly come up with same implementation (unique tracking token) the moment they hear that problem description.
Their write-up just irks me because it's misrepresenting the patent (silly as it may still be).
