It's already been done for the Z80 several times with WizNet modules. http://susowa.homeftp.net/index.php/kcnet-75/z80-tcpip-159.html?start=5
http://spectrum.alioth.net/doc/index.php/Spectranet These two implementations each use some extra "glue" logic - KCNet talks to the Wiznet module through a PPI chip and Spectranet has a separate microprocessor. This allows the implementations to be moved to different systems. But since the Wiznet modules essentially have the same address, data, and chip select lines as an SRAM chip, I don't see why a direct IO or memory mapped version couldn't be produced for an S-100 card. The chip itself supports both modes.
