Have an architecture consisting of 3 (for now) processes: one monitoring external comms, one to process messages in/out 
another communicating to another device via serial port. I think that I want one "master" app to get started and then 
have it init the other processes which then create and join their own partitions, start threads etc. Question is where 
is the preferred file location to put these 4 processes; put the "master" one place & the others somewhere else? or does
 it really matter?

Thx
