Yes, I suspected that was the only real way to do it. I just don't do C though, so it's a quite involved for me to learn. Then there would be the requirement for the user to patch the kernel(!) before using my program... not the best idea for a simple-to-use program.

Besides, I don't do C so the learning curve would be way to steep.

But thanks for putting me on the right track, I'll now start looking into setting up a proxy and hijacking the DNS.
