I agree and that such is a possibility and is something that Grant 
/Edwards/ -- the OP -- will need to make a judgement call on.

That's about what I had expected.  Not many, if any, ready built tools 
for transferring raw Ethernet frames.  Though plenty of scaffolding to 
create it.

That's about what I remember.

Thank you for finding and sharing that milestone.

Aside:  I don't like using "milestone" to describe the point that was 
removed.  Particularly something I think is good.

This is the USB version of the Laplink cable concept.

Decidedly different than the old serial & parallel versions of which 
I've used many times.  LapLink, INTERLNK.EXE & INTERSVR.EXE, and '95's 
Direct Cable Connection used them.  I suspect there may have been more 
that I'm not aware of.

Interesting.

I'm not sure why a separate program was needed.  Maybe it didn't 
monopolize the server side the same way that INTERSVR.EXE did.

Because INTERLNK.EXE would map a drive to the server and return control 
to the command prompt / batch script allowing use of the new drive letter.

Interesting.

This is most likely to be the lease problematic considering that it 
turns the Linux end into a /special/ USB flash drive.

Is it wrong that the first thing that came to mind when reading the OP's 
post is UUCP with as high speed serial as possible?

I wonder if the USB LapLink (type) cable or USB On The Go gadget cables 
could present as a multi-megabit serial interface.
