+The purpose of this PEG document is to give a short overview of existing 
structured
+P2P overlays which have an open source implementation. 
 
 The reason for creating this PEG document is that the current implementation 
 of GISP [5]_ seems to have (too) many obvious security exploits. For us this 
 indiciates that GISP is in early phase of development. Therefore we need to 
-examine other available overlays which have an implementation in hope for 
-finding a more mature tightly structured P2P platform.
