I can see how it can be stored securely, but how would distribution after recovery be accomplished?
In an envelope? Or by sending me a one-time random https-link where I can retrieve it myself? Sounds like more trouble compared to what can be gained from it. Wouldn't it be just as easy to send a one time password that needs to be changed... Too impracitcal to be implemented in a real-world situation... This is probably why I still wouldn't hesitate to say that it is insecure if it is in clear text. Even though I must give you credit for having shown a way to do it. ;-) I am sure someone will come and beat me with saying that they already did this. :-p Ppl do all sorts of crazy stuff just because they can...
