Better description coming soon, but please check out 

The QRU server feature of APRSISCE/32 provides objects on-demand based 
on the APRS-known location and query group desired by a remote 
APRS-message capable operator.  We're still working out standardized 
group names, but ?HOSP (Hospitals) and ?PD (Police Departments) are two 
of the top runners.

Send an APRS message to QRU containing "?INFO 20000" to see what QRU 
servers have what groups available within 20,000 miles of your current 
location. Obviously, you'll need to have transmitted a position beacon 
that has been heard by a QRU server to get any answers.
