Add support for transproxy

[lokeshh]

Its really pain for some apps to set proxy on them and even after that its not guaranteed that they would work. One amazing feature that I would love to have is let the apps never know that their running behind a proxy, i.e. everything would work as if there's no proxy. In short I'm proposing for a transparent proxy. Although I'm not sure if its possible. May be using iptables?! What do you say?

We tried touching this issue, but our focus was to just set the proxy in all the softwares that support proxy. But the idea of transproxy sounds interesting to me.

Transproxy sounds really interesting. It's not the focus of ProxyHelper for now though. I suppose it should be possible via iptables, routing all TCP traffic through a system socket which in turn is binded with the proxyserver (a bit like sshuttle). I don't know much about it though, if you want to implement it, do it! it would be cool!
