Can Multibit be set to use a SOCKS proxy on OSX? I'd like to route my multibit traffic through TOR, but have been unsuccessful finding out if it's possible. It's certainly not in the GUI settings on OSX.
Unfortunately there is a library used in MultiBit/ bitcoinj for networking (called netty) that does not support SOCKS proxies. Thus currently you cannot set up MultiBit to use Tor.

It is something we want to support so there are plans afoot to refactor the code and use a different networking library that does support SOCKS proxies.
