I would like to put my corporate legal infrastructe on an internal secure conferencing system. News (with crypto-signed articles) is ideal. Without a "destroy all copies" concept I cannot do this.
Um.. You can't give people copies of something and then destroy all copies of that thing unless you can trust those people to destroy *their* copies of it on your request. If you *can* trust them to do this, then the ratings-system solution I mentioned a minute ago will work. Just ask everyone to set their useragents to "delete" when they encounter a "deleted, signed The Boss" mark on an article.
