Hello people interested in this topic,

I made a wiki page for Naming Systems  here:
  https://trac.torproject.org/projects/tor/wiki/doc/OnionServiceNamingSystems

Feel free to start adding information and links and make it look nicer.

Let's try to build a good knowledge base that will help us take informed
decisions. Please try to maintain some sort of consistent structure through the
document.

(In the unlikely case where the doc gets out of hand, I will try to find some
time to curate it.)

Thanks! :)
