The ircDDB software was developed to enable fast and reliable call sign routing. The "Live Log" and the "LastHeard" list are just a "by-product" of this functionality. After February 20th, 2011, every ham radio operator can choose whether his/her call sign will appear in the "Live Log" and the "LastHeard" list or not. So, this is just about visibility of your data on the Internet. Call sign routing works the same way as before. You don't have to enable Internet visibility for your call sign in order to use a repeater.
