I would like to *EMPHATICALLY* agree!

You have a problem requiring expertise in at least three diverse 
disciplines:
   1. physically installing the system
   2. designing the system to operate as required under nominal 
conditions
       CRITICAL subtask: just what is specified goal?
   3. securing system against:
      a. accidentally being compromised
      b. malicious attacks
         To understand how being "rural" is *NO* protection, 
insert respective
         antenna elevations into sites such as
         http://www.calculatoredge.com/electronics/lineofsight.htm

At a minimum, Google "securing Debian".
