npapi plugin for chrome proxy settings

As you may already know, chrome does not have a proxy management interface and it uses the system's proxy settings for that. If you want to change those settings from an extension you need to develop a plugin which communicates with NPAPI in order to apply settings. The plugin exposes it's methods/functions to javascript which can be used inside the extension to retrieve the current proxy/set the proxy. I need such a plugin which will work on all major platforms (linux, windows, mac) and both on x86, x64 based systems. I only need two functions exposed so it should be fairly simple for a C++ programmer to get into the basics and build them. First function: getCurrentProxy - will return the current proxy set into the browser/system respectively: 1. ip address 2. port 3. protocol (http, socks4, socks5) setProxy (ip_address, port, protocol) - will set the system proxy based on the parameters received. Will also validate the ip_address to be a valid ip, port to be a numerical value between 2 and 5 digits and protocol must be in the list: (http, socks4, socks5) As a help to get you started you may read: [login to view URL] - chrome guide on adding npapi plugins http://www.firebreath.org/display/documentation/FireBreath+Home - NPAPI framework Any questions, just ask.
