No need to annotate the data on the tor network; each user's client software chooses exit points on its own, so you could just have the user tell the client "for request to this location, use one of these routers". This could easily go into the client config file, for example. Automatic location affinity would be even cooler, if we could do it; see http://freehaven.net/doc/routing-zones/routing-zones.ps . > Also, what do people think of the idea that > special DNS names could be used to impose such constraints, like using > "www.google.com.[exitnodeconstraint].constraint" for the hostname of > hosts that you want to reach via a certain constrained set of ExitNodes? Possibly; I'm not as sure that this is what you really want. Why not just do it at the configuration level? yrs, -- Nick Mathewson (PGP key changed on 15Aug2004; see http://wangafu.net/key.txt)
