I'm sorry, but how do you run a BTC client behind Tor? My Tor installation comes with a bundled browser, and from what I gather the only communications being scrambled are the ones the Tor browser makes... Am I wrong?
How would one (easily

) make MultiBit "speak" through Tor?
On ubuntu listen it is as simple as installing tor, making sure it is started, and the adding proxy=127.0.0.1:9050 to your bitcoin.conf
OR starting bitcoind with flag -proxy=127.0.0.1:9050
Don't know about windows/Mac, but it shouldn't be too hard... Tor is for encrypting/anonymizin all internet traffic, not just for web sites.
Ultra-cool-tip of the day: you can create a server, which is _only_ set up as a tor hidden service. This means that you can only ssh to it through tor, etc etc.
