Is it possible to somehow configure Tor to use USA-based proxies only? If not, does anyone know of another multi-proxy program out there that's any good?
There are multi-proxy programs out there. I can't tell you them off hand, there is a good firefox plugin (can't remember the name) that switches proxies for you that isn't TOR related. You can use Access Diver which is a free script and there are several others that tell you where your proxy is from. You can try Charon which is a favorite in the proxy circles, I can't vouch for it since I haven't used it in about a year. I like Access Diver because I've been using it for about 5 years off and on.
I was reading recently that someone was actively developing a toolset for TOR to allow it to be configured by Country; exactly what most folks want. I can't remember the tool though --sorry.
essential_clix I'm not sure if this method still works with the latest version of Tor or not, but this is how we did it a few months ago. These exit nodes are old too so you'll have to go through the tor map yourself and find new ones. The following causes tor to ONLY use the listed exit nodes even though the rest of the route still gets bounced around various nodes. This worked (slowly tho) for doing CL a while back.
The following goes at the very very bottom of the torrc file...
I use a program called ProxyFirewall for both private (with username and password) and public for my proxies. It will intercept most, if not all, winsock calls when any programs connect to the net and ask if you want to allow the process with or without using a proxy. Any programs it doesn't detect itself, like some of the multithreaded bots out there, you can manually add to its list by browsing to the program file.
For Tor use all you do is install the full Tor/Vidalia as normal and add the above lines in my previous post in the torrc file if you wish to make it country specific, and then after installing proxyfirewall (see link below), open PF and go to the Open Proxy tab and add a HTTP(S) proxy of 127.0.0.1:8118 (Tors internal connection url on localhost), then you install the program you're trying to proxify and run it and when PF intercepts it you select...
Use Proxy Server, select Single in the dropdown list, then select the Open Proxy for Tor you added earlier, UNtick all the boxes below as Tor autorotates (or you can do it manually from the system tray menu) and click on OK.
And you're all set. Remember though everyone that Tor may be semi-anonymous but it sure isn't safe to put any sensitive information across. There've been several exposes recently about people (including the CIA apparently) setting up tor exit nodes of their own and being able to browse their own logs for all YOUR info and passwords. Be warned!

Sounds more like you answered his question in regards to proxy judges, not how to configure tor for USA only..
