Not quite sure why you would say this. There are some things that I agree need a lot of research before you even try, but ethernet switches aren't particularly hard to set up or use. As long as you check the power requirements and get a suitable regulator, power supply shouldn't be an issue. After that, most switches are basically just plug and play. Sure you can then get into static IPs and all that jazz for whatever coprocessors you have plugged into the switch, but that is different from using the switch itself.
I agree about making sure that the roboRIO is connected directly to the radio, as it removes a point of failure. Especially now that the radio firmware is (hopefully) fixed so both ports always work.
