No real reason. (I'm only concerned with 2 or 3 Linux boxes and a couple
of Windows machines that connect periodically.)  It just seemed to be
the most elegant and extensible way to go.

BTW, I installed SAMBA for the windows machines (use this with the Linux
machines, too.  No problem in Samba with accessing the servers using
their names.  Wonder why ssh is so different.

Thanks,

Bobby
