Check out the Lucent Portmasters if you still want to go that 
direction.  Old hardware but they work quite well.  They typically have 
10BaseT network connections, and you can set a series of telnet ports to 
forward to each individual connected serial port.

You may need some DB25-DB9 adapters, depending on the equipment you're 
hooking up.
