 This is not random!

 Copied/pasted from Terminal:

  Hello, children of the world!     //_=_=_\\   Olá, crianças do mundo!

 [olpc at xo-0D-54-FD ~]$ sudo hexdump /dev/hwrng[[BR]]

 0000000 ffff ffff ffff ffff ffff ffff ffff ffff[[BR]]

 ^C[olpc at xo-0D-54-FD ~]$ [[BR]]

 So, I also got just FF's, and only 16 bytes worth.  If this is random, I'm
 gonna buy a lottery ticket.
