The problem is that even with sources that don't require registration, they pull down the original links in a matter of days or weeks. Right now we have a rich source of archived information. If John creates a program that goes back and excerpts previously posted articles, then it's gone. The links to the source will no longer exist in most cases. What would be nice would be to have document hosts on the web much like image hosts. Originals could be stored on a password protected server, but the posted links would be accesible.
