[ snip ] I'd toyed with the bandwidth idea... let's say that we create 0xffff:1, :2, :3, and :4 to mean sub-T1, T3, OC3, and >= OC12. Arbitrary and simplified for sake of example. Whenever a router forwards, it tags with the appropriate speed. Thus, if :1 is set, you _know_ this path has a sub-T1 link. Of course, some places might use bogus tags to try hiding their connectivity... but an upstream could use a route-map to let the truth escape. Thus, with proper administration by upstreams, !set{:1|:2|:3|:4} would indicate no participants along the way. However, if this were to gain momentum among the biggest three dozen ASen, I think that we'd have a very accurate system. Even the top one dozen could do a very good job, considering how many connect directly to them...
