[aprssig] Multi control station situational awareness - For mobiles? or homes without power?

[Robert Bruninga]

There sounds like two paths emerging.

- Come-as-you are with APRS radios in the mobile as the end terminal unit
   Everybody has one

- Invent something new with PC's, clients, Pi's, displays, for use at home
(or front seat mobile?
  Nobody has one
