That is generally the concept we have been using for over 15 years in multiple configurations using Serial Device servers. They convert the serial ports to IP data on the network and using virtual serial ports on the computers. We use MOXA devices:

In the timing shack we have multiple Alge S4's, Output for display and an output for datalog all connected to a moxa that is nailed to the wall and connected to the network. This allows the laptop timing to be on the network, but does not require you to be in the timing shack, you could be at the start or in the lodge.
We also have connected the start/finish hand timing systems to a moxa so we can compute hand times in real time and EET for every racer.
There are a ton of uses for these devices and is permitted in the rules but for non-sanctioned races, the possibilities are endless.
Also of note, the MOXA will allow up to 4 connections per port (timer), so you can use an Alge S4 with the MC-18 multi channel and time 8 courses using 4 sets of dual software/laptops or use 2 timers and each other would be the A/B system for the opposite course etc........
