I've put up a couple little bits to add to Radio's proxy support:

* An application + script that reads OSX's current proxy status and
puts that info in the proper places in a Frontier/Radio install. This
is probably most useful for people who swap proxy settings based on
network locations. http://www.wiredfool.com/discuss/msgReader$1622

* Support for SOCKS (version 4) proxies. Socks proxies are at the tcp
connection layer, rather than the application layer like an http proxy.
Most notably, this is the dynamic proxy provided by ssh.
