Have checked out your recommendation and not sure I like it. It doesn't give the plain simple information the Spoofstick does, but it does contact it's home base for every page you display, which can add considerably to your internet traffic.
Also, the code seems to have some holes in it, such that if it cannot contact its home site it goes into a loop trying, using up 100% of the cpu and making your system unusable. Therefore if netcraft went off the air, or your isp decided to block it, or whatever, you could have no internet access unless you uninstall it.
