tortunnel sets up a local proxy routed through a Tor exit node:
This is useful in cases where you might want some very low level of anonymity and don’t want to deal with the performance implications of using Tor’s full three-hop circuits.
Usage is simple, torproxy -p 5060 -r to use a random Tor exit node and torproxy -p 5060 -n <ip> to use a specific exit node.

I might give this a try using anon.xmission.com, which is a Tor exit node run by XMission, a local ISP here in Utah. While I’m not an XMission customer, my Comcast connection gets good speedtest.net results to XMission.
