I even did an experiment. I have version 3.58 installed on top of the official 3.5. I clicked on "Internet," then selected one of the three servers, and that's it. And even more so for TCP/IP. We've played it a million times.
Ask those who play to share the game. It doesn't need to be installed. Just copy it and play over the network in versions 3.5 or 3.58 without any problems.
