but you could do it via ettercap, this is probably going straight overkill, but configure ettercap to search for strings over port 80 traffic and replace them with other strings...

We've done it via unencrypted traffic w/o problems so far, but its really simple once you figure it out and run it a couple times...

Other than that, i know you can use IE's ocx files inside like VB apps, but im still pretty sure you wont be able to control the content.

Perhaps another program like net nanny will give ya some ideas ? or even check planet-source-code, or similar... Sorry couldnt be more help
