Without a proper sharing system (Unity) you will have problems. Its not just about allowing the other boxes to see the media. They need to have the bandwidth to work with the media. (Low res might play ok, but full hd is going to be tough on a normal network) But beyond any speed issues you have, is the actual sharing of the project and the data base for the media. You would have to be very organized in who is working on a project, as you can’t have two people using the same project at the same time, unless you use a proper system. (unity) Also, you would have difficulty “sharing” the media, as everytime one person rights a render to the media drive, everyone else’ database will have to update. Tough to edit when your data base is always updating because someone did something.
We actually tried this a couple of years ago. Had a fibre connection to two shared drive arrays, and two avids trying to use them. Who ever launched first, got control of the project. As soon as the other guy tried to jump in the crashing started. What we ended up doing was giving write access to 1 array each, and read access to the other array each. We also had to copy the project to both boxes, and stay very organized as to what bins we modified. In the end, it was not worth the headache, and we just stayed separated.
