I respectfully disagree. What it requires is some mechanism to get updates back to "authorized" server(s), and those "authorized" servers need to determine what to do with the reports. This does not need to be real-time. Near-time would suffice IMO. The interesting issue with regards to this component is indeed not the transport mechanism, but rather dealing with the influx of reports, and mitigating DOS's through floods of bogus reports. This is where things like the "web-of-trust" concept comes in handy. Sorry, but this is definitely getting off the operational charter of NANOG, so I'll stop. :-) There are a few people that have expressed interest in exploring this further. If anyone is interested drop me a line privately. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ Patrick Greenwell Asking the wrong questions is the leading cause of wrong answers \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
