Sorry, it kind of went off on an unrelated thread.
After the tsunamis the governments got hot for subscription-driven
event notification in a geospatial context, primarily for disasters
but now they want to take it much further and apply such a framework
to all manner of thing that may have nothing to do with disasters per
se. Child abductions are among the very first things they want to do
this with, for example. Fox News will be all over this (*rolls
eyes*). The basic model looks like this:
The individual subscribes to any number of specific event feeds with
a geospatial context, voluntarily or involuntarily depending on the
feed and the government. Some of these feeds are for very specific
types of events, other ones are descriptive and abstract. As the
individual travels around, the events they see are the intersection
of their subscription profile with the event, and their geospatial
location with the geospatial area of the event as defined in the
feed. The problem is scaling up the ability to determine if an
individuals subscription and event intersect in near real-time, and
this needs to have a significant amount of centralization as a
practical matter and political control along the usual boundaries is
a big issue. Both the events *and* the subscriptions will be
floating around in space constantly, and this needs to be sorted out
if they are going to use it for anything remotely resembling all they
want to use it for. There is a full expectation that the private
sector will rapidly find uses for it too, for good or ill,
piggybacking on the government mandated interfaces.
Do not worry about signing up for this service, it will be
mandatorily built in to your cell service at a minimum.
