I'm not sure how this is really new. Everything he's describing has been possible for years with a laptop. I guess "plug computer" might make it a little cheaper and a little easier to conceal?

If anything, I'd say plug computers are good for security, if they're making people more aware of how god awful stupid the "eggshell" model of putting all your efforts into perimeter security really is.

Unfortunately, instead of focusing on security their internal servers and app, my bet is most "enterprises" will instead respond by just extending the eggshell with greater lockdown of end-user PC's. :-(
