We tried to outline some of the challenges of building such a system in our NANOG52 presentation:


In particular see slide 4. where we tried to lay down what we think the requirements are for a socially acceptable
reputation system.  

With a bit of luck we might be able to announce the release of our system before the next NANOG mtg, but in 
my opinion collating host reputation reports is just a small and the easiest part of the effort.  The key is in 
solving the challenges of allowing (and incentivizing) participation and being robust to false information

Comments are welcome.
