Example commercial applications:
     Safety, health, wellness, personal security, etc..
     Ingle International (Ingle Insurance) has already expressed interest in
     this invention, and they could, for example, be the remote service
     provider.  In this application, a remote call centre or crisis centre
     is setup 1-way (e.g. covert) or 2-way (e.g. where an attacker or
     assailant is made aware of the remote connection and actually is being
     talked to by the remote party).
     Another example application is to help in addressing bullying.
     Presently persons with special needs are often bullied others,
     inluding police or security guards, due to the fact that people with
     special needs often act differently than others, and acting differently
     is seen as suspicious.
     
     The PSD might have saved the life of
     Sammy Yatim,
     and others suffering from mental challenges, who otherwise end up
     being shot dead by police because of differences in their responses
     or actions.  In this case, the PSD makes it known to the potential
     attacker (whether the attacker is a civilian or a guard or an officer)
     that the attacker is being watched by a remote entity.
     Much like the big screen TV at the entrance to a shopping mall, the
     PSD can include a wearable video screen that shows a video conference
     call with a remote call centre like Ingle International,
     a company that already has extensive experience with tense standoffs
     like hostage negotions and hostile attackers.
