I gather from the FAQ that this software consists of a client and servers (both closed-source). The servers are operated by the Haystack people in safe countries. The client appears like an HTTP proxy to the user's web browser, but then it encrypts the user's web traffic and hides it among innocuous traffic, some or all of which goes to the Haystack servers. I still don't get how the client traffic is supposed to look unconspicuous while still most of it goes to Haystack servers. Do they pad their client-server traffic with ten times as much Google searches for cute kitty pictures? If not, what keeps the suppressive government from installing their own Haystack client on a spare computer and blacklisting every server the client connects to as an illegal proxy?
