 Problem Statement:  with the evolution of the internet / dail-up to remote devices/services.


 Opportunity : ability to validate ...devices , network-based remote-support-services with 
               a digital-handshake for reliability of service or other network based activities.

               eg: some of the classes of devices(tape-drives) or infrastructure as part of data-center support, network
                   based updates much on the line's of remote-software-upgrade on operating-systems....the reliability
                   or ability to roll back to orginal firmware ...as a controlable feature from device-management-interface's.


Note: The above problem statement having been encountered in various scenarios
      and detailed in various 'Proof of concepts' as mentioned in

        ....apply appropriate
      'use-case' modeling, rationalize and arrive at a workable and feasible 
       solution both commercially and techinically viable.
