That Would be Possible..

What would be optimal. would be for the Buffers to be mapped into a 
Cartridge Space, so that a Small Control Program could Switch between 
the Cartridge ( I/O Buffers ) and the CoCo's RAM.


The WizNet W5100 has a 32K Internal Memory Map that can be setup to be 
Memory Mapped ( called Direct Bus Interface mode ) to the Host CPU.

The ESP8266 is UART or SPI/I2C Interface, which can't really be Memory 
Mapped without other Hardware, like a MCU...
