Ben sent around on the mailing list a mostly point-by-point analysis of the original SSSCA (which became the CBDTPA). The article you link to seems focussed on games. Think of typical computing tools, though:
Text editor -- It must only copy text in a manner that retains the original copyright controls as the original work. Copy-and-paste goes out the window for all practical purposes.
File systems -- cp becomes illegal for all practical purposes.
CD/DVD players/recorders -- Must support copyright control from the laser all the way through the magnet on the speaker. (Yes, hardware and software.) Which means it will have to be connected to the manufacturer's or media distributer's system to ask permission for copying. Which will mean the hardare is already in place to be able to enforce per-play controls. (Yay, pay-per-view)
Basically, no general purpose computing hardware or software. Locked-down appliances only. Software will all be of the type in your VCR. You sort of know it's there, because it has an interface, but you can't do anything with it except select the menu options.
