Thanks for the reply.  That seems to be a good solution - effectively
two back-to-back USB-serial cables (e.g. what I use now, a Belkin
F5U109).  It seems so obvious with the pervasiveness of USB that I am
concerned about the seeming lack of implementations (at least there is
little in the HOWTOs and newsgroups).  Am I missing something?  I have a
hard time believing there are small server sites that do not have this
issue.

Maybe a PPP connection over USB is the preferred solution?  I have done
this with a PDA (Intel PXA255) but that contains a gadget controller.
