On the subject of trusted hardware: m-o-o-t does this, by booting and running from a verified CD on an ordinary PC/Mac box. No expensive chips. BTW, there was a M$ patent for Tsomewhere, can I claim prior? We're getting close to anonymity (PA). Too. :) Nah, that's not big enough. SMILE! Add that to the mix, remembering that TYABBAYABBA won't work 100%, and some geeky people will be able to redistribute *m*o*v*i*e*s* without being caught. Then their friends will do so too (their friends), and if it's anonymous.... (and I mean _really_ anonymous...) I'm going to buy some more of this fine beer now. I'll probably wish I hadn't posted this, at some time in the future. Peter -- peter@m-o-o-t.org http://www.m-o-o-t.org ps no-one has commented on my one-way-functions post. Either you're all mathematicians, or you don't care.
