We tried to outline some of the challenges of building such a system in our
NANOG52 presentation:
http://www.merit.edu/networkresearch/papers/pdf/2011/NANOG52_reputation-nanog.pdf
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
injection.
I've actually encountered a system that was accepted for operational use
once. Bad data was added at some point (bound to happen) and the system
was shut down.
Thanks for sharing your slides, keep up the good work!
Gadi.
