Are you saying this second  machine has no rj54 for a network cable?

Then that leaves a serial port, or possibly a usb to serial at the 2nd's 
location. This is a bit unusual, but between a linux or windows pc, and 
an old trs-80 color computer, has been done. The software is called 
drivewire, and it adds 14 i/o channels good for 115k kilobit speeds. 
This includes a channel dedicated for printing text, which I wrote a 
script for to pass it off to cups, a channel for general midi use, and 
which can be handed off to timidity, and 14 more channels which can be 
used as text terminals, or disk drives, including the ability to "mount" 
an  image of the coco's file system as if it was another floppy drive, 
but can be a 130 megabyte file.

Drivewire facilitates all that. Its GPL, written in jave so it should be 
pretty portable. But for machines other than the coco's, will need 
substitutes written for its output modules. On the coco's it runs over 
the bit banger port, so any machine with a bit banging serial port would 
be a candidate to become a drivewire client.
