Now I do wonder how they deal with that in Seatalk. It runs an actual bus over 2 wires (with multiple talkers and all).
Collision control - something that doesn't exist within the NMEA 0183 standards but does exist on the 2000 standards. With regards to putting multiple listeners on the same wire, I'd probably hesitate to do that. Unless you are really good at crimping and creating taps, a single additional listener could cause a large voltage drop and then NONE of your devices would work. I'd lean heavily towards an active multiplexer. I hate tracing electrical gremlins.
