Proxy Pre-Setting in Add-on ??

Hi, I've had a request to have multiple proxy presettings in the livestreams add-on.

I'm not sure how to go about. My first thought was to change xbmc's network setting to the presets but this doesn't seem doable from an add-on, or is it I guess one could build the proxy in urllib then pipe to the player, seems there should be an easier way. Is it possible to pass the proxy info in the url to the player 'url | proxy info' ?

Any ideas?
