I run my Quicksilver as a gateway to the net. This allows me to only register one MAC address with the unscrupulous network masters of my school. I have the firewall on and all forms of sharing turned off. Internet is passed to my router via a second ethernet card. Is it possible to enable file, print sharing, etc. on only one of my cards? I'd like to have it enabled for the other computers on my network and still be Mr. HermitMac to the outside world.

    Yes you can do this, but you have to avoid Apple's firewall setup, and write the ipfw rules yourself. Not necessarily an easy task. 'man ipfw' in the terminal is one place to start.. then head out onto the web for more informaiton. You will probably want to create an item in /Library/StartupItems/ so that your rules get established at every boot.
