With the recent takedown of silkroad, I am pondering on how anonymous you actually can be on the Tor Network. Other more legal or moral uses such as anonymity as a right, or avoiding censorship. These users do in fact face the same problem if it possible to get through the anonymizing layers of Tor.
Note: I just read the question regarding the reason for silkroad takedown was a leaked IP address. So lets restrict the scope of this question to attacks on the Tor protocol itself, rather than misconfigured http servers...
What my question is, what impact would running "Tor within Tor" make to anonymity, and usability? Would the anonymity (if measurable) be doubled?
To examplify what I mean, the command:
should be enough to run a tor instance where all communication is wrapped inside tor.
