A new blog from that sounds promising:

The term ‘true name’ comes from magical traditions where it is believed that knowledge is power, and one of the surest ways to get knowledge of something was to have a name for it. A name being not only a definition but a contagious and associative link with the thing. The common words we use to refer to things are nothing more than a rudimentary label, whereas the true name of that thing is akin to a complete understanding of its entire being. If such a thing were possible. In Vinge’s story this amounted to knowing the users real name and thus where their body was jacked in; you could do anything in the Other Plane just as long as no one could actually kill you. Though you could say that about the real world too.
