Edward Snowden Explains How to Reclaim Privacy
What I don't get about Tor is that if your adversary can see all Internet packets, all the time, wouldn't it be trivial for them to find the real source and destination of a Tor packet using it's meta-data (size,timestamp,etc...)?  For example, a packet of size X was sent from host 1 to host 2 and immediately after, a similarly sized packet was sent from host 2 to host 3, etc...  I think of Tor more like a tool to avoid a specific server from finding who you are, and not the government.
