Rooting Nexus to use ProxyDroid?

view story

http://forums.androidcentral.com – Hello This page explains that the best way to let web browsers access the Net through a proxy on an Android smartphone is to 1) root the phone and 2) install ProxyDroid. I want to access web sites from my Galaxy Nexus through a web filter to rewrite web pages on the fly, but since Privoxy isn't really ported/supported on Android, a second-best solution I thought of is to keep a small Linux appliance at home running Privoxy, and configuring my Nexus to use that remote proxy. But before I go ahead, I'd like to make sure I'm not about to brick/break my phone since I'm happy with the stoc (HowTos)
