I hear that computers can be programed to create and maintain a list of 
sites one's own customers visit frequently.  The same computer (so I'm 
told) could also determine which AS has authority to announce the IPs 
for each site.  The same computer (so I'm told) could also watch for 
announcements from other ASs for the IPs from this up-to-date "widely 
visited sites" list, and send out an alert or otherwise take action when 
such an announcement was seen.  It would be wonderful if someone would 
write and share code to do just this.
