I don't want to get anyone in trouble, but if the browser (and the browser's history and cache) and the web pages are both local to your USB key, there'll be nothing to monitor for network/internet activity. The browser won't be going out to the internet, just to local files on your USB key. That's the whole idea behind downloading the Solvelior/Sage SRD, is so that there is no network/internet traffic to contend with; it's all right there at the speed of USB2 transfer, and it works even when your computer isn't connected to the internet.
