A Networked Game would require "tackling" several Topics at once..
Luckily, this is one of my favorite topics...

If you remember back to 1993, and the MS-DOS DOOM, there was a Two
Player Mode that used the RS-232 Serial Port and a Null Modem Cable...
As I Recall, ( and a little Google Search confirmed ), that Data
Exchange for DOOM on RS-232 is at 8 N 1 9600. Which is 960 Characters
per second.. ( with 8 Data Bits, 1 Stop Bit and No Parity )
Each Computer was Playing the Full Game, only the Player State ( and
changes to the Environment ) were being Exchanged between the Two
Machines.. The Bit-Banger Serial Port on the CoCo is capable of 9600
bps, so I think Networked CoCos are very possible.

Does VCC or Mame for the CoCo support the Serial Ports?? This would
also possible for networked gaming..

DriveWire is a Possible Network Transport, so is the Lantronix, UDS-10s
also the CoCoNIC in development or even another Networking option,
including Wireless... ( ESP 8266 WiFi Modules )

Starting with MAME/MESS, and adding Network Support would be the start
of the Goal.. But each Emulated Platform would need a Network Layer
Designed.. And Games ( and other applications ) would need to be
Patched or Designed to support the Networking.

A World Wide Audience... With Retro Computing becoming a Specilized
Interest, our "User Group" is not just local, but World Wide..
Networking Classic Hardware is another way of Socializing with "Members
of our User Group"...

My notes I have been "compiling" for the past year are to make
supporting Multiple Platforms a Goal from the Beginning.. I am hoping
that is "Big Enough"
