Check this out, this is an awesome concept. Tried it on my desktop and worked fine. Meaning that I was on the remote network without needing to use tsocks/proxychains or to configure any proxy paramter... Although it only passes TCP packet through the tunnel so DNS searches leaks in clear text. Still a very good way to avoid the proxy configuration mess on N900.

It uses Python and IPTable so it might work on Maemo (I hope).
