• The metadata problem
• Secret Bonding
• Secret Rendez-vous
• How to discover your friends on the network (using phone numbers for exemples) without giving away your friendlist.
  Part1: Associate your phone number, email address or other identification mean with a public key. This could be done using web-of-trust. (This is a topic on its own)
  Part2: Compute a kind of "secret rendez-vous point" (H(K_a^k_b) == H(K_b^k_a)) from your public key (eg: associated with your phone number) with all your friends "phone-numbers" public key and publish it
  Part3: Finding a published token linking our phone number to someone's else means that our this is indeed our friend's public key
  [It is true indeed that after Part1, we don't need Part2 and Part3 because we already know our friends public keys]
