   I still wonder, if you record your entire life, when will you have time to replay it?
   
   I can't help but think of Spaceballs...
   
   "What the hell am I looking at? When does this happen in my life?"
   "Now. You're looking at now, sir. Everything that happens now, is happening now."
   "What happened to then?"
   "We passed then."
   "When?"
   "Just now. We're at now, now."
   ...

   In other words, the usual meaningless hype.
   
   Why waste space on this?

   Similar countermethod discussed for "post office a

   In Bruce Schneier's most recent (and as always excellent) Crypto-Gram, a "post office attack" was described which had what appears to be a similar countermethod as the Microsoft anti-spam method mentioned. Here is the issue (it is the lead article): http://www.counterpane.com/crypto-gram-0304.html If you follow the link for the "scripted attacks" paper at the end of the first article (URL pasted below) you will find that in section 5.4 it walks you through one possible "client puzzle". These wouldn't work nearly as well for email since the sending server and the receiving server almost never communicate directly. But I assume any proposed solution would require that the receiving server be able to open a direct communicaton with the sending server once an email was received in order to initiate the puzzle. http://www.avirubin.com/scripted.attacks.pdf Seems like you'd have to work out how to eliminate IP spoofing in email for it to work (not likely) or at least have servers keep an index of what they sent (not easy) ... possibly explaining why it is still in research.

   recording everything would be a boon

   You don't record everything for the sake of playing it all back. You record everything so that next week, when you ask "whom did I run into on the way to lunch last thursday?", you can look back and find out.
   
   BTW the solve-a-puzzle spam idea isn't new.
