The distance now include some samples with 100 nodes

-For Ulysse : useful is spelled with only ONE l and not two.....
-            + ALL files should now respect a maximum 80 rows convention

 Bugs :
     When no peer is avalaible, the setup crash without the --no-boot option
-    => see below
+    G : see below
+    U : this is still a bug to be solved
 
 To be done :
     Use an algorithm to choose which connections to keep and/or establish
     instead of pure randomness
+    
     Find a name for the project : the projet is ( or should be ) independant
     from vifib, openvpn, babel, and so should the name; btw we aim to build a
     distributed, scalable, resilient VPN.... ( if it helps with the name )
+    
     Replace comments at the beginning of functions with docstrings & give all
     fn docstrings
+    
     Use the server events ( client connection/deconnection ) to do something
     useful
+    
     In peers DB, remove some peers when they are too many of them -> remove the
     dead peers
-    Use a timeout for the peersDB -> ?, removing the dead peers should be enough
+    
+    Use a timeout for the peersDB 
+    G : removing the dead peers should be enough
+    U : I was speaking of the server peers DB
+    
     Specify a lease duration in ForwardViaUPnP
+    
     Handle LAN internally in order not to have catastrophic results ....

-    U : Contact the server using vifibnet and not the underlying network when

     U : The peer DB size should depend on the number of connection and the

     G : ?! I don't agree, the db size should be proportional ( with a factor
         like 0.01 or less ) to the total number of peers in the entire network,
         with maybe a max size.
