I am not sure how far your along with your install. I have been using different MUX, WiFi and combined units made by a guy here in Australia for a couple of years now. I have found them to be very reliable and his back up warranty and support is very good.
Here are a couple of units you may be able to make use of, these units are very affordable when compared to those items made by the bigger European company's.
2 Port NMEA MUX to WiFi Bridge allows you to connect 2 separate NMEA devices and transmit your NMEA data to all of your WiFi devices. I have used one of these to send AIS and Seatalk data (after conversion in the ST->NMEA) to my Pi. I powered the units off the seatalk bus as the current draw is very low. I cant imagine you will need the ST->NMEA I just mentioned how I set up to give you an idea.
Bi-Directional NMEA to WiFi Bridge allows you to transmit your NMEA data and it can also receive NMEA sentences back.
YakMUX 3 Port NMEA 0183 Combiner MUX with USB, allows different combinations of input and out put speed etc of NMEA data.
When or if you want the wired data to and from the MUX for input to the PI there are several different RS422 or RS485 converters on Ebay and prices start at $5

Only those who go too far can possibly tell you how far one can go
