[tor-dev] Little question

Sorry, to bump in, I know you are busy, but being a tor-node I had to ask:

Some guy just posted on mailing list an conceptual attack on tor, which certainly would require the corruption of great deal of tor-nodes and data analysis, but something that appeared possible gor gov-alike:

And then someone pointed that this is part of tor model of security and known problem, but one that should raise flags if attempted. Could you point me some link where I can find more? Besides reading source code?

Thank you!
