Also, more of a general BNC ethernet question, if I daisy-chain the computers together with RG-58 cables and T-connectors with 50 ohm terminators at both ends of the chain, is that all I need to make the network work?
Well, from an infrastructure side, yes, that's all you need to make the physical network. It's down to the software/drivers after that. Afraid I've no idea about the software involved...
