Dennis,

> You still aren't clear on WHAT this communication IS...

Ah.  The answer to that is simple: Anything I want.    Datapackets normally
do not care what they contain. :-)

And that is all I intended the connection with the RPi as a middle-man to
be: To be able to send data either way, but without either of the two sides
being able to see each other.   No more, no less.
