GUEST IWTK:

I am not one of the Clones, but I do have knowledge and experience in this area.

The answer to your question is: it depends -- but yes, it is more than theoretically possible. I've done it myself on more than one occassion.

Having said that, I'm not going to say anymore. To do so would involve a long, technical discussion and possibly teaching you things that I have neither the time nor the inclination to do. If you truly want to know the mechanics of this, I suggest a good course in the administration of Unix-based networks since Unix, in its various flavors, has long been the de facto standard for the Internet.
