Thanks! I can always use another good documentary.
In return, I can recommend The KGB, The Computer, and Me, based on the excellent book The Cuckoo's Egg.
I can also recommend all of the documentaries done by Jason Scott (Get Lamp, BBS: The Documentary, Going Cardboard (although he only edited that: He's director on the rest), and DEFCON: The Documentary)
