Just a little thought that just occured to me:

When the DA is formed, Hermione has everyone sign the list, which is charmed to reveal the name of the person who betrays the group. Wouldn't it be quite a conveniet Charm to be used by any other secret group? Like the Order? Every member simply puts their name down on a list, and in case he or she betrays the Order, a Charm would show it immediately. Thus, the danger of being infiltrated by a spy would be significantly minimised. (Peter Pettigrew with his face covered with ugly pus boils...)

Any thoughts?
