DNS over Tor

One additional idea, along similar lines, might be to compare the results of standard DNS with Tor'd DNS for all DNS lookups and create a log file with any discrepancies...
In other words, if/when there is a difference, log that.
You would lose DNS privacy with this method, but, if you were say, in China, and your regular non-Tor'd DNS was blocked or re-routed (whether accidentally or intentionally) then at least your log file would tell you that something was up...
In fact, it might be an interesting experiment for an Internet researcher to gather as many domain names as possible, then look them up via both regular DNS and Tor'd DNS, and note any discrepancies...
And, the same experiment could be repeated in different countries...
The Chinese are oppressively good at inspecting packets. I fear they'll start exporting the tech and skills eventually to the most evil leaders on Earth as just another export. Tor is somewhat out of reach for the average Chinese whistleblower.
