  1. Users queue up to connect with another user( randomly)
  2. preference can be < 100km, 50km etc
  3. users who iniate a connect must be placed into a queue for first come first serve basis
  4. users connecting can be global( all around the world)
  5. matching up users must be fast and efficient.
