The IESG has no problem with the publication of 'Survey of Research 
towards Robust Peer-to-Peer Networks: Search Methods' 
<draft-irtf-p2prg-survey-search-02.txt> as an Informational RFC. 

The IESG would also like the IRSG or RFC-Editor to review the comments in 
the datatracker 
(https://datatracker.ietf.org/public/pidtracker.cgi?command=view_id&dTag=14535&rfc_flag=0) 
related to this document and determine whether or not they merit 
incorporation into the document. Comments may exist in both the ballot 
and the comment log.

Technical Summary
 
  The pace of research on peer-to-peer (P2P) networking in the last 
  five years warrants a critical survey. P2P has the makings of a 
  disruptive technology - it can aggregate enormous storage and 
  processing resources while minimizing entry and scaling costs. 

  Failures are common amongst massive numbers of distributed peers, 
  though the impact of individual failures may be less than in 
  conventional architectures. Thus the key to realizing P2P's potential 
  in applications other than casual file sharing is robustness. 

  P2P search methods are first couched within an overall P2P taxonomy. 
  P2P indexes for simple key lookup are assessed, including those based 
  on Plaxton trees, rings, tori, butterflies, de Bruijn graphs and skip 
  graphs. Similarly, P2P indexes for keyword lookup, information 
  retrieval and data management are explored. Finally, early efforts to 
  optimize range, multi-attribute, join and aggregation queries over 
  P2P indexes are reviewed. Insofar as they are available in the 
  primary literature, robustness mechanisms and metrics are highlighted
  throughout. However, the low-level mechanisms that most affect  
  robustness are not well isolated in the literature. Recommendations
  are given for future research.
