That's one way to do it. However, a terminal server usually works in the reverse direction -- as in allowing one to telnet, over TCP/IP, to a serial device.
The application you describe, assuming you do not have your own LAN, would be better served by a pair of 8-port or so statMUX boxes. Their purpose in life is to multiplex multiple serial ports over a single, dedicated, 4-wire data circuit. I had a couple doing exactly that here, between the lab and the garage, before I installed the micro-serial thingy from LANTronix and the code-operated switch.
RE-PC has a nice assortment of MultiTech StatMUXes at the moment, and I know they're in the $10-or-less category per unit. Want to send me some $$ and I'll see if I can snare you a pair?
Keep the peace(es).
