Ah, well, your original email never mentioned phones :-). In that case
UUCP is not going to work well.
I was assuming that Bob (and everyone else) has a laptop. In that case,
he would carry his mail spool around with him, and send and receive
emails via UUCP whenever he is in the vicinity of another system.
