No. These are for different protocol families. /servers is for the default system servers. What you want to do is to use private servers -- they are not supposed to be in /servers. You can basically put them anywhere -- most likely in the home directory, or perhaps somewhere in /var or in /tmp... There is really nothing special you need to do to be able to run multiple pfinet:s. It's already possible right now -- there is just no mechanism to tell a process to use an alternate server instead of the default one...

That's fine for the start. > I wonder how much work it could be? And how do I start? Well, I must remind you that you were supposed to provide a schedule in your application... I accepted your not doing so, because the task description was very unspecific, and you were not really in a position to provide a schedule without discussing things first; but now that you have an idea what you will be actually working on, you should be able to come up with a rough schedule... I suggest you start with the server overriding mechanism, as it's the easier part, and there is less to discuss... -antrik-
